apm821xx: add support for kernel 5.10 for testing
This patch copies over refreshed patches from 5.4. - dropped crypto patches (they got upstreamed) - dropped renesas USB 3 firmware loader (they got upstreamed) - NAND now needs extra device-properties for ECC settings. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

Subject: [PATCH] powerpc: bootwrapper: force gzip as mkimage's compression
|
||||
method
|
||||
|
||||
Due to CONFIG_KERNEL_XZ symbol, the bootwrapper code tries to
|
||||
instruct the mkimage to use the xz compression, which isn't
|
||||
supported. This patch forces the gzip compression, which is
|
||||
supported and doesn't matter because the generated uImage for
|
||||
the apm821xx target gets ignored as the OpenWrt toolchain will
|
||||
do separate U-Boot kernel images for each device individually.
