ARM: pxa: Fix OneNAND SPL builds

2014-01-13T11:39:10Z

The OneNAND SPL used on PXA is slightly obscure. Due to the OneNAND limitation, where we have only the first 1KiB of the OneNAND available upon power-up as a memory-mapped area, from which the CPU starts executing, we place only the most essential code into this first 1KiB . This code copies the rest of the SPL into SRAM and jumps to it. This code is stored in section .text.0 . The rest of the SPL is stored in section .text.1 . When running the OBJCOPY on the SPL, it will preserve only .text section, but the .text.0 and .text.1 are stripped away from the result, thus making the SPL binary empty. The patch adds additional -j parameters to the OBJCOPY for PXA during the SPL build, which will preserve the .text.0 and .text.1 sections. Moreover, this patch also adds missing functions into the .text.0 section, since otherwise the PXA270 with 1KiB-window OneNAND won't be able to boot.

ARM: pxa: prevent PXA270 occasional reboot freezes

2013-12-18T15:00:37Z

Erratum 71 of PXA270M Processor Family Specification Update (April 19, 2010) explains that watchdog reset time is just 8us insead of 10ms in EMTS. If SDRAM is not reset, it causes memory bus congestion and the device hangs. We put SDRAM in selfresh mode before watchdog reset, removing potential freezes.

ARM: refactor compiler options in config.mk

2013-09-23T15:03:05Z

Every ARM cpu config.mk (arch/arm/cpu/{CPUDIR}/config.mk) defines: PLATFORM_RELFLAGS += -fno-common -ffixed-r8 -msoft-float So, this patch moves the common compiler options to arch/arm/config.mk. Signed-off-by: Masahiro Yamada

pxa: use -mcpu=xscale compiler option

2013-06-22T13:25:28Z

Pass '-mcpu=xscale' to the compiler instead of march and mtune. This will cause gcc to define the __XSCALE__ macro. Signed-off-by: Mike Dunn

pxa: turn icache off in cpu_init_crit()

2013-06-22T13:25:28Z

The comment in the low-level initialization function cpu_init_crit() says that the caches are being disabled, but (oddly) the icache is actually turned on. This is probably not a good idea prior to relocating code, so this patch turns it off. Tested on the pxa270. Signed-off-by: Mike Dunn
