Subject: [RFC/query] ARM: enable AUTO_ZRELADDR at 16MB aligned of RAM ?
Date: Thu, 17 Oct 2013 22:18:06 +0800 [thread overview]
Message-ID: <20131017221806.514ca45a@xhacker> (raw)
Hi all,
I need your help about where the 128MB limitation of AUTO_ZRELADDR comes from? IOW,
why
mov r4, pc
and r4, r4, #0xf8000000
rather than
mov r4, pc
and r4, r4, #0xff000000
Can we make the following change to arch/arm/boot/compressed/head.S?
@ determine final kernel image address
mov r4, pc
- and r4, r4, #0xf8000000
+ and r4, r4, #0xff000000
add r4, r4, #TEXT_OFFSET
#else
ldr r4, =zreladdr
Thanks in advance,
Jisheng
