Subject: [PATCH 166/219] feat:Support mmz partition resize
|
|
|
|
Changelogs:
|
|
1.It is able to resize the mmz partition via uboot command:"fdt mmz <name> <addr> <size>".
|
|
The "@upper,lower" will be added as suffix to mmz partition name. This name does NOT
|
|
conform to mmz partition naming conventions.
|
|
So, change the eswin_memblock.c to truncate the string before '@' character and use it as
|
|
the partition name.
|
