Subject: sh: Fix address to decompress at when CONFIG_32BIT=y
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b161313ae8d9c64de589d1de72f975210ce37b48;p=linux-beck.git

sh: Fix address to decompress at when CONFIG_32BIT=y

When running in 32BIT mode the P1SEG region doesn't necessarily provide
a window onto RAM (it depends how the bootloader setup the PMB). The
correct location to place the decompressed kernel is the physical
address of _text.
