This patch bumps the 4.4 kernel from .28 to .30 and refreshes the patches. Compile-tested on ar71xx, x86/64, ramips/mt7621, brcm47xx and kirkwood. Run-tested on ar71xx & ramips/mt7621, brcm47xx and kirkwood (last two confirmed by P. Wassi). Signed-off-by: Stijn Segers <francesco.borromini@inventati.org>

Subject: [PATCH] MIPS: store the appended dtb address in a variable
|
|
|
|
Instead of rewriting the arguments to match the UHI spec, store the
|
|
address of a appended or UHI supplied dtb in fw_supplied_dtb.
|
|
|
|
That way the original bootloader arugments are kept intact while still
|
|
making the use of an appended dtb invisible for mach code.
|
|
|
|
Mach code can still find out if it is an appended dtb by comparing
|
|
fw_arg1 with fw_supplied_dtb.
