Not all SoCs reset peripherals like that; don't
assume they do.
Hi!
This patch changes the default behaviour of Cortex-M3 soft-reset. More
details can be found in thread STM32 reset_config.
I've tested that with STM32 - everything works fine, peripherals are
reset as they should be (with standard cfg files).

HI,
I want to debug u-boot for s3c6410 with openocd 0.4.0, but I fount that the
resume command timeout some time.
So I use a simple program to test, it runs on the internal sram .
I use openocd to download init.bin to the internal sram , and use the
resume command to run it.
The steps
The log is:
load_image init/init.bin 0x0c00
776 bytes written at address 0x0c00
downloaded 776 bytes in 0.046875s (16.167 kb/s)
resume 0x0c00
halt
target state: halted
target halted in ARM state due to debug-request, current mode: Supervisor
cpsr: 0x21d3 pc: 0x0cd8
resume
Please try the master branch.
0.4.0 is a bit old for reporting bugs to the list.

After bootstrap and configure (per instructions), I get
build failures on Linux with an
all but pure clone of mainline. (Quilt and git report only
a patch to the git ignore file, not to any code.)
Same config I've used on this machine most of the last year.

It should print the instructions on how to build and install

Shouldn't the code assume that this standard mechanism works as the

Hi!
I've thought about that whole patch which adds cortex-m3 reset_config
command and I think it's not very good now (if I correctly understand
its behavior).
Let's say, that there is a chip which has some problems with
SYSRESETREQ, so the target config file forces VECTRESET (which is not a
