Follow-ups

After reboot command in Linux, bf51x halt at address 0xef000e48. No kernel code
is at that address. It looks it is uboot that halt other than kernel. But, maybe
kernel doesn't clean up something before jump to bootrom.
--- Sonic Zhang 2009-01-09 05:38:37
0xEF000000 ~ 0xEF007FFF BOOTROM (32K bytes)
Maybe a bug in BOOTROM code?
--- Mike Frysinger 2009-01-09 06:04:56
try putting a ssync before the "raise 1" in
linux-2.6.x/arch/blackfin/kernel/reboot.c
--- Sonic Zhang 2009-01-13 00:19:46
There is no official anomaly list on ADI web site. But anomally 05000353 still
exists on bf518 v0.0.
05000353 - bfrom_SysControl() Firmware Function Performs Improper System
Reset:
DESCRIPTION:
The bfrom_SysControl() firmware function does not properly execute a software
reset and cannot be used to perform system reset of the
processor. Some side effects that may be observed due to this are that not all
System MMRs are reset correctly.
APPLIES TO REVISION(S):
0.0, 0.1
--- Sonic Zhang 2009-01-13 00:21:26
In addition, bfin_gpio_reset_spi0_ssel1() should be extended to support other
SSEL PIN.
--- Sonic Zhang 2009-01-13 00:39:08
Fixed
--- Mike Frysinger 2009-01-13 06:13:33
i really dont think anomaly 353 still applies. the change that was made in the
bootrom for that anomaly was made in the bf51x.
--- Mike Frysinger 2009-01-15 00:14:50
apparently the bf51x bootrom does not perform a system reset if the bits in
SWRST are cleared. ive changed our core code to stop reading SWRST since the
info is available in SYSCR on newer parts and e-mailed benno about the issue.
--- Yi Li 2009-01-20 22:20:03
fixed and close.
--- Mingquan Pan 2009-02-06 05:44:34
why I am still seeing this bug on trunk head on bf518f-ezbrd?

--- Mike Frysinger 2011-05-02 00:03:10
the kernel now uses bfrom_SoftReset() to reboot the part rather than just
"raise 1" when the anomalies dont exist (like the bf51x).
back to grace to verify things.

Since it still remains, so add Mike.

i'm not sure your kernel test is still new enough. the kernel was changed after
2.6.39-rc5 was merged. please make sure 2.6.39-rc7 fails.

i still cant reproduce this. with a bf518f-0.0 board, i did:
(0) hit hardware reset button
(1) press space to interrupt u-boot booting (2011.03-gbe60713)
(2) type 'run ramboot' to boot up a kernel
(3) u-boot loads up a recent build (2.6.39-ADI-2011R1-pre-gc1a6090)
(4) type some stuff into the kernel prompt and then type 'reboot'
(5) go to (1)
i repeated this four times in a row and it worked everytime. so back to grace
to try and describe the exact steps she's running and describe exactly what
she's doing so i can reproduce over here.

Yeah, reboot on the latest kernel is ok on my side too.
The bf518 board finally can run regression repeatedly now. Great fix.
