From d8ba40cfcdd509e7e1ed68878cb93d9a81e245b6 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Mon, 30 Mar 2015 20:20:15 +0000 Subject: brcm63xx: use relocate to move the kernel back to start of ram Appearently the kernel only uses kernel above it, so moving it to an higher address causes a lot of unavailable memory (#19327). Also move the on-flash kernel to 0x80a0000, as newer CFEs don't like uncompressing there (net-booting an ELF kernel is fine, though).

Traditionally the kernel will get linked to and loaded -at offset 64k. -This will pose a problem if the kernel size reaches 4 MiB - 64 kB, as -CFE will start overwriting itself. This can easily happen by including a -ramdisk image in the kernel. -While for net-booted elf kernels this can be worked around by wrapping -them in a lzma boot loader, on-flash images require the kernel to be -lzma compressed. This would cause inefficient double compression. - -Luckily we have full control over where the kernel will be extracted to -and the entry point to be called, so move the kernel to behind CFE. ---- - arch/mips/bcm63xx/Platform | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - ---- a/arch/mips/bcm63xx/Platform -+++ b/arch/mips/bcm63xx/Platform -@@ -4,4 +4,4 @@ - platform-$(CONFIG_BCM63XX) += bcm63xx/ - cflags-$(CONFIG_BCM63XX) += \ - -I$(srctree)/arch/mips/include/asm/mach-bcm63xx/ --load-$(CONFIG_BCM63XX) := 0xffffffff80010000 -+load-$(CONFIG_BCM63XX) := 0xffffffff80800000 -- cgit v1.2.3
