pxa: Save lr register in relocate_code function

2013-01-14T23:22:00Z

When u-boot is compiled for PXA25x processor, pxa/start.S is calling cpu_init_crit by BL instruction. BL is overwriting lr register so relocate_code is going into infinite loop. This patch preservs lr register in r12 before calling cpu_init_crit and after function returns restores it. Signed-off-by: Lukasz Dalek Acked-by: Marek Vasut

arm: Move bootstage record for board_init_f() to after arch_cpu_init()

2013-01-10T21:27:41Z

The timer may be inited in arch_cpu_init() so it is not safe to make a bootstage mark before this is called. Arrange the code to fix this. Note: The question was raised as to why we don't keep all archs in sync. PowerPC doesn't have specific bootstage markers at present (although it does use boot progress). I hope that the generic board series will solve this problem in general, but in the meantime this is a real problem, and only in ARM. We now get a correct time for board_init_f: Timer summary in microseconds: Mark Elapsed Stage 0 0 reset 100,000 100,000 spl_start 848,530 748,530 board_init_f 907,301 58,771 board_init_r 910,478 3,177 board_init Signed-off-by: Simon Glass

arm: Make interrupts.o and reset.o in libarm also appear in SPL

SPL u-boot may call do_reset() which depends on interrupts.o and reset.o. So make them also appear in SPL. Signed-off-by: Tom Wai-Hong Tam Signed-off-by: Simon Glass

arm: Add CONFIG_DISPLAY_BOARDINFO_LATE to display board info on LCD

2013-01-10T21:22:01Z

This option displays board info after stdio is running, so that it will appear on the LCD. If it is displayed earlier, the board info will appear on the serial console but not on the LCD. Here follows a blow-by-blow description. 1a.

We may be able to rearrange things some other way one day, but at present this seems like a convenient way of getting the required behaviour. Signed-off-by: Simon Glass
