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

mx25: Fix boot hang by avoiding vector relocation

2015-01-08T18:50:17Z

Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") mx25pdk hangs like this: CPU: Freescale i.MX25 rev1.2 at 399 MHz Reset cause: WDOG Board: MX25PDK I2C: ready DRAM: 64 MiB (hangs) Add a specific relocate_vectors macro that skips the vector relocation, as the i.MX25 SoC does not provide RAM at the high vectors address (0xFFFF0000), and (0x00000000) maps to ROM. This allows mx25 to boot again. Acked-By: Bill Pringlemeir Signed-off-by: Fabio Estevam

mx25: Remove empty line after printing the reset cause

2015-01-08T16:00:45Z

Currently there is an unneeded empty line after printing the reset cause: U-Boot 2015.01-rc4-00080-g0551a93 (Jan 06 2015 - 13:04:19) CPU: Freescale i.MX25 rev1.2 at 399 MHz Reset cause: POR Board: MX25PDK I2C: ready DRAM: 64 MiB MMC: FSL_SDHC: 0 Remove the extra "\n" when printing the reset cause.

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: UniPhier: fix SRAM size on support card

2015-01-08T14:01:21Z

The max size of available memories on slot0 and slot1 is 32MB because - EA[25] signal is not output on the save-pin mode which is used PH1-LD4 or later SoCs. - EA[25] signal is not connected by the limitation (or bug?) of the PLD logic of DCC support card. Signed-off-by: Masahiro Yamada
