Subject: [PATCH 08/10] rpi: fix dram bank initialization
|
||||
|
||||
To update the dram bank information from device-tree we use
|
||||
fdtdec_decode_ram_size() which expectes the the size-cells and
|
||||
address-cells to be defined in the memory node. For normal system RAM
|
||||
these values are defined in the root node. When the values differ from
|
||||
the default values defined in the spec, we can end up with wrong RAM
|
||||
bank information.
|
||||
|
||||
Switch to the "standard" way to update the RAM bank information to
|
||||
avoid this.

||||

Subject: [PATCH 09/10] rpi: Enable DRAM bank initialization on arm64
|
||||
|
||||
Up to now we only update the DRAM banks when we are define
|
||||
CONFIG_BCM2711. But our one binary approach uses a config that supports
|
||||
BCM2837 and BCM2711. As a result we only see one gibibyte of RAM on
|
||||
Raspberry Pi 4, even if it has more RAM.
|
||||
Fix this by calling dram_init_banksize.

Subject: [PATCH 10/10] ARM: defconfig: Fix 32bit config for RPi4
|
||||
|
||||
The rpi_4_32b_defconfig states that only one DRAM bank is present. This
|
||||
leads to a wrong configuration of the available DRAM. Fix this by
|
||||
setting the DRAM bank config accordingly.
