[U-Boot] [PATCH] arm: add IPL support

2013-12-03 Thread Kuo-Jung Su
Initial Program Loader (IPL) usually runs with .text and .rodata in ROM, while .data and .bss reside in RAM. This patch uses the AT keyword to specify load address, and a small code snippet in crt0.S to restore .data section at runtime. Example usage: Assume the target device has a 4KB ROM at 0x0
