Subject: [PATCH] nvmem: u-boot-env: fix crc32_data_offset on redundant
|
|
u-boot-env
|
|
|
|
The Western Digital MyBook Live (PowerPC 464/APM82181)
|
|
has a set of redundant u-boot-env. Loading up the driver
|
|
the following error:
|
|
|
|
| u_boot_env: Invalid calculated CRC32: 0x4f8f2c86 (expected: 0x98b14514)
|
|
| u_boot_env: probe of partition@1e000 failed with error -22
|
|
|
|
Looking up the userspace libubootenv utilities source [0],
|
|
it looks like the "mark" or "flag" is not part of the
|
|
crc32 sum... which is unfortunate :(
