Subject: [PATCH] gta01-no_nand_partitions.patch
|
|
[PATCH] support mtd NAND commandline partitions for S3C2410
|
|
|
|
This patch adds support for the mtd NAND core standard method of passing
|
|
partition table information from the bootloader into the kernel by using
|
|
the kernel commandline.
|
|
|
|
The board specific code can still manually override and provide a fixed
|
|
partition table, so this patch will behave backwards compatible.
