arm: build arch memset/memcpy in Thumb2 mode

2015-01-09T15:20:22Z

Resynchronize memcpy/memset with kernel 3.17 and build them in Thumb2 mode (unified syntax). Those assembler files can be built and linked in ARM mode too, however when calling them from Thumb2 built code, the stack got corrupted and the copy did not succeed (the exact details have not been traced back). However, the Linux kernel builds those files in Thumb2 mode. Hence U-Boot should build them in Thumb2 mode too when CONFIG_SYS_THUMB_BUILD is set. To build the files without warning, some assembler instructions had to be replaced with their UAL compliant variant (thanks Jeroen for this input). To build the file in Thumb2 mode the implicit-it=always option need to be set to generate Thumb2 compliant IT instructions where needed. We add this option to the general AFLAGS when building for Thumb2. Reviewed-by: Simon Glass Tested-by: Simon Glass Signed-off-by: Stefan Agner

ARM: UniPhier: add UART initialization routine for low-level debug

2015-01-08T14:01:56Z

The low-level debugging functions are useful to debug the early boot stage where the full UART driver is not available. UniPhier SoCs need to initialize the UART port 0 to use this feature. The initialization routine is called at the very entry of the lowlevel_init(). Signed-off-by: Masahiro Yamada

ARM: UniPhier: enable output of system bus

2015-01-08T14:01:45Z

For NAND boot on PH1-LD4, PH1-sLD8, and some other SoCs, the output of the system bus is disabled by default. It must be enabled by software to have access to the system bus. Signed-off-by: Masahiro Yamada

ARM: OMAP4: Panda: rework DMM logic

2015-01-05T20:13:45Z

Part of DMM logic is reuse from commit 47a4bea6af77b01d59a410d09a4c34b2dd14cf50 ("ARM: omap4: Update sdram setting for panda rev A6") Which broke SDP4430 with ES2.3 (uses old DDR). So, to maintain support for newer DDR used in Panda ES rev B3, we should, in addition to the commit 675cc77a3ae45e8b0ec17128563264d4a509f628 ("ARM:OMAP4+: panda-es: Support Rev B3 Elpida DDR2 RAM"), DDR timings, also do DMM configuration specific to Panda.

ARM: bootm: do not add PSCI to fdt when booting in secure mode.

2015-01-05T20:02:03Z

Commit 8bc347e2ec17 "ARM: bootm: Allow booting in secure mode on hyp capable systems" added the capability to select nonsec vs sec mode boot via an environment var. There is a subtle gotcha with this functionality, which is that the PSCI nodes are still created in the fdt (via armv7_update_dt->fdt_psci) even when booting in secure mode. Which means that if the kernel is PSCI aware then it will fail to boot because it will try and do PSCI from secure world, which won't work. This likely didn't get noticed before because the original purpose was to support booting the legacy linux-sunxi kernels which don't understand PSCI. To fix expose boot_nonsec (renaming with armv7_ prefix) outside of bootm.c and use from the virt-dt code. As well as avoiding the creation of the PSCI nodes we should also avoid reserving the secure RAM, so do so.
