Dear all:
I recently port uboot on my platform.
I have several questions below:
1. why some cpu need reload code to dram rerunning, but some doesn't need.
As far as I know, qemu-mips, lib_mips/board.c will but
arm,lib_arm/board.c, doesn't.
2. what are the gadget and musb used for under drivers/
uot;b xx'.
If uboot don't handle these exceptions, how the kernel knows these events?
appreciate your kind help,
miloody

Dear all:
I have trace interrupt/Fiq vector in uboot based on smdk2410.
after we save user registers, we jump to following functions I

But these 2 functions seems not really handle the irq/fiq, would

Hi:
I got a arm platform, arm940t, which is pretty much like arm920t, except
without mmu.
So I decide to port some arm920t uboot to my platform and smdk2410 sounds a
good choice.
The reason why I take off this config is I just want to build a bare uboot
without any driver except UART, the console
Dear all:
I try to build make smdk2410_config without CONFIG_S3C2410 define.
I see the include path is BUILD_DIR/include, BUILD_DIR/include2 and
uboot/include.
I have set CONFIG_S3C2410=0 in include/configs/smdk2410.h and also check it
as 0 in autoconf.mk, too.
But the final image I build still run
Dear all:
I have some question about what arm will do while exceptions happen.
In the document, ARM Architecture Reference Manual located at
http://www.arm.com/miscPDFs/14128.pdf, there are some actions will be done
when IRQ interrupt happened, A2.6.8.
Below is excerpted from it:
R14_irq = addres
Dear all:
I try to run uboot, configed as smdk2410, on armulator, compatible as
ARM7TDMI, but I receive "undefined instructions" exception while running the
code "bl cpu_init_crit" in start.S.
The ISA of both smk2410 and arm920t is V4T and bl is the instruction that
already supported form V1.

Dear all:
I get an arm platform from my friend and it is not in the list of boards in
include folder.
I intend to make a pure uboot, without including any driver but only basic
cpu setting and uboot commands supported. But I cannot see any config option
in Makefile.
I know I may choose any config i
