Subject: [PATCH 01/36] TI: Add, use a DEFAULT_LINUX_BOOT_ENV environment
string
To deal with a reoccurring problem properly we need to specify addresses
for the Linux kernel, Flatted Device Tree and ramdisk that obey the
constraints within the kernel's Documentation/arm/Booting file but also
make sure that we relocate things within a valid address range.
It is possible with these addresses to also set fdt_high and initrd_high
to the value of 0xffffffff. We don't do this by default to allow for
the most likely success of people using custom addresses however.

Subject: [PATCH 10/36] add header with a generic set of boot commands defined.
As the next step in a generic config we are introducing a set of generic boot
paramaters. Depending on the hardwares configuration, booting from supported
hardware will be enabled, mmc, usb, sata, scsi, ide, pxe and dhcp.
There is nothing to stop this being extended to support nand and any other
type of storage that comes along. An ideal future enhancement will be to
allow the user to dynamically reorder the boot devices, and allow one off
boots. for example simply be able to pxe boot to reinstall

Subject: [PATCH 11/36] add README.distro file
Add documentation on how to setup a system to use the generic distro
configs and boot commands. This spells out what is needed to make a
system conformant, but does not limit the board to only the defaults.

+
+Generic distro configuration
+----------------------------
+
+configuring
+-----------
+To configure a board to run the generic distro setup and enable generic distros
+to easily support your board.
+
+you will need to include a pair of headers to enable the boot environment and
+configuration options needed. It is best to only include when not doing an
+SPL build.
+
+#ifndef CONFIG_SPL_BUILD
+#include <config_distro_defaults.h>
+#include <config_distro_bootcmd.h>
+#endif
+
+There is some memory addresses you will need to define in
+CONFIG_EXTRA_ENV_SETTINGS
+fdt_addr:
+Optional, If specified a dtb to boot the system must be available at the given
+address.
+
+fdt_addr_r:
+Mandatory, This is the location where the sysboot/pxeboot with load the dtb to,
+using the fdtdir/devicetreedir or fdt/devicetree options in the pxe/extlinux
+config file. The location can be anywhere in ram it just needs to not overlap
+with anything, allowing 1 megabyte seems to be a safe option.
+
+ramdisk_addr_r:
+Mandatory, This is the location where the sysboot/pxeboot with load the
+initramfs to, using the initrd option in the pxe/extlinux config file, the
+location of the initramfs does not matter, there needs to be enough room to be
+able to store any image. Making the image the last item stored should allow for
+any initramfs to fit and not overwrite anything else.
+
+kernel_addr_r:
+Mandatory, This is the location where the sysboot/pxeboot with load the kernel
+to,using the kernel option in the pxe/extlinux config file, the location of the
+kernel needs to
+
+pxe_addr_r:
+Mandatory, used by the PXE code to hold the pxelinux config file. The location
+can be anywhere in ram it just needs to not overlap with anything, allowing 1
+megabyte seems to be a safe option.
+
+scriptaddr:
+Mandatory, used to load boot.scr to The location can be anywhere in ram it just
+needs to not overlap with anything, allowing 1 megabyte seems to be a safe
+option.
+
+suggested mapping:
+For suggestions on memory locations for arm systems you must follow the
+guidelines specified in Documentation/arm/Booting in the Linux kernel tree.
+For other architectures you must follow the guidelines for the architecture.
+
+make sure you also include BOOTCMDS_COMMON in CONFIG_EXTRA_ENV_SETTINGS
+
+You should not set initrd_high and fdt_high to 0xffffffff as the user should
+not need to edit the memory locations having the initramfs and dtb being
+relocatable is best to ensure the system will boot in all situations.
+
+booting your system
+-------------------
+in the most simplest form CONFIG_BOOTCOMMAND just needs one line
+
+"for target in ${boot_targets}; do run bootcmd_${target}; done "
+
+you can run any setup before going through the targets for example run a
+command to set "fdtfile" variable for the dtb for your board.

+U-Boot for Utilite
+--------------------
+
+This file contains information for the port of U-Boot to the Utilite.
+
+Utilite is a development board that has three variants based on the following
+SoCs: mx6 quad, mx6 dual lite and mx6 solo.
+
+For more details about Utilite, please refer to:
+http://www.utilite.org/
+
+Building U-boot for Utilite
+-----------------------------
+
+To build U-Boot for the Utilite Dual Lite version:
+
+$ make utilite_dl_config
+$ make
+
+To build U-Boot for the Utilite Solo version:
+
+$ make utilite_solo_config
+$ make
+
+To build U-Boot for the Utilite Quad version:
+
+$ make utilite_quad_config
+$ make
+
+Flashing U-boot into the SD card
+--------------------------------
+
+- After the 'make' command completes, the generated 'u-boot.imx' binary must be
+flashed into the SD card;
+
+$ sudo dd if=u-boot.imx of=/dev/mmcblk0 bs=512 seek=2; sync
+
+(Note - the SD card node may vary, so adjust this as needed).
+
+- Insert the SD card into the slot located in the bottom of the board (same side
+as the mx6 processor)
+
+- Connect the serial cable to the host PC
+
+- Power up the board and U-boot messages will appear in the serial console.

Subject: [PATCH 18/36] sunxi: add sun7i clocks and timer support.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds the basic clocks and timer support for the Allwinner A20
(sun7i) processor. This code will not been compiled until the build is hooked
up in a later patch. It has been split out to keep the patches manageable.
Some of the code here is common to multiple sunxi subarchtectures, hence files
are named sun4i which is the earliest similar variant.

Subject: [PATCH 21/36] sunxi: add sun7i cpu, board and start of day support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds generic board, start of day and basic build system support for
the Allwinner A20 (sun7i) processor. This code will not been compiled until the
build is hooked up in a later patch. It has been split out to keep the patches
manageable.

Subject: [PATCH 27/36] ARM: HYP/non-sec: move switch to non-sec to the last
boot phase
Having the switch to non-secure in the "prep" phase is causing
all kind of troubles, as that stage can be called multiple times.
Instead, move the switch to non-secure to the last possible phase,
when there is no turning back anymore.

Subject: [PATCH 29/36] ARM: non-sec: reset CNTVOFF to zero
Before switching to non-secure, make sure that CNTVOFF is set
to zero on all CPUs. Otherwise, kernel running in non-secure
without HYP enabled (hence using virtual timers) may observe
timers that are not synchronized, effectively seeing time
going backward...

Subject: [PATCH 32/36] ARM: HYP/non-sec: allow relocation to secure RAM
The current non-sec switching code suffers from one major issue:
it cannot run in secure RAM, as a large part of u-boot still needs
to be run while we're switched to non-secure.
This patch reworks the whole HYP/non-secure strategy by:
- making sure the secure code is the *last* thing u-boot executes
before entering the payload
- performing an exception return from secure mode directly into
the payload
- allowing the code to be dynamically relocated to secure RAM
before switching to non-secure.
This involves quite a bit of horrible code, specially as u-boot
relocation is quite primitive.

Subject: [PATCH 33/36] ARM: HYP/non-sec: add generic ARMv7 PSCI code
Implement core support for PSCI. As this is generic code, it doesn't
implement anything really useful (all the functions are returning
Not Implemented).

Subject: [PATCH 34/36] ARM: HYP/non-sec: add the option for a second-stage
monitor
Allow the switch to a second stage secure monitor just before
switching to non-secure.
This allows a resident piece of firmware to be active once the
kernel has been entered (the u-boot monitor is dead anyway,
its pages being reused).

fixup function
Some architecture needs extra device tree setup. Instead of adding
yet another hook, convert arch_fixup_memory_node to be a generic
FDT fixup function.

Generate the PSCI node in the device tree.
Also add a reserve section for the "secure" code that lives in
in normal RAM, so that the kernel knows it'd better not trip on
it.

Subject: [PATCH 37/37] PXE: syslinux implenets some keywords found in configs
we do not support
distros write out extlinux.conf files and documentation lists pxe config
options we do not support. today the user gets ugly messages like:
Ignoring unknown command: ui
Ignoring malformed menu command: autoboot
Ignoring malformed menu command: hidden
Ignoring unknown command: totaltimeout
instead fo printing the messages for known but unsupported options lets
silently pass over them.

Subject: [PATCH 38/38] PXE: distros implementing syslinux will be using raw
kernels and initramfs
Since we are not detecting if the image is raw or wrapped and we expect
distros to be using raw images attempt bootz before bootm. This prevents
the user from getting a confusing error message:
Wrong Image Format for sysboot command
ERROR: can't get kernel image!

So far, only supporting the CPU_ON method.
Other functions can be added later.

CNTFRQ needs to be properly configured on all CPUs. Otherwise,
virtual machines hoping to find valuable information on secondary
CPUs will be disapointed...
