| | | * ARM: Auto calculate ZRELADDR and provide option for exceptionsEric Miao2010-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As long as the zImage is placed within the 128MB range from the start of memory, ZRELADDR (Address where the decompressed kernel will be placed, usually == PHYS_OFFSET + TEXT_OFFSET) can be determined at run-time by masking PC with 0xf80000000. Running through all the Makefile.boot, all those zreladdr-y addresses == 0x[0-f][08]00_0000 + TEXT_OFFSET can be determined at run-time. Option CONFIG_AUTO_ZRELADDR and CONFIG_ZRELADDR are introduced, CONFIG_ZRELADDR _must_ be explicitly specified if: - ((zreladdr-y - TEXT_OFFSET) & ~0xf8000000) != 0, which means masking PC with 0xf8000000 will result in an incorrect address. Currently this is only a problem on u300. - or the assumption of the zImage being loaded by the bootloader within the first 128MB of RAM is incorrect - or when ZBOOT_ROM is used, where the above assumption is usually wrong.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I tried to get this running to debug the regression introduced by e7db7b4 without success. But this has several problems that make it hard to fix: - lib/decompress_inflate.c includes in-kernel headers that make it difficult to compile for user space. - the binary formats changed both in kernel and user space and at least for the kernel side there isn't only a single variant.
