2012-10-03arm: rmobile: Add support Renesas R8A7740Nobuhiro Iwamatsu
Renesas R8A7740 is CPU with Cortex-A9. This supports the basic register definition and GPIO. Signed-off-by: Hideyuki Sano <hideyuki.sano.dn@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2012-10-03arm: rmobile: Add support TMU base timer functionNobuhiro Iwamatsu
Some rmobile SoC has TMU base timer function. This supports TMU. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2012-10-03arm: rmobile: Change initializing ICCICR registerNobuhiro Iwamatsu
There is rmobile without ICCICR. ICCICR is initialized only when ICCICR is defined. Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2012-10-03arm: rmobile: kzm9g: separate cpu_rev to integer and fractionTetsuyuki Kobayashi
According to SoC document, revision info is separated to integer part and fracton part. So I separete rmobile_get_cpu_rev() to rmobile_get_cpu_rev_integer() and rmobile_get_cpu_rev_fraction().

CPU info register was read wrongly by mistake. And function rmobile_get_cpu_rev() was not called properly. Signed-off-by: Tetsuyuki Kobayashi <koba@kmckk.co.jp> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2012-10-03arm: rmobile: Support build with gcc-4.6 or laterNobuhiro Iwamatsu
Latest rmobile code was tested by using old gcc (gcc-4.4). When we use gcc-4.6 (or later), the build is made, but does not work. This solves a problem not to work by add -march=armv5 to compiple option when we built in gcc-4.6 (or later). I tested by linaro's compiler version 2012.04-20120426.

2012-10-01am33xx: Fix fetching of mmc1 bootmode from bootrom for AM33XXJoel A Fernandes
U-boot should not ignore getting the bootmode passed on from the bootrom. With this, U-boot SPL knows it was loaded from MMC1 and use this info to read full U-boot from MMC1 as well.

2012-09-27SPL: NAND: Move arch/arm/cpu/armv7/omap-common/spl_nand.c to common/splTom Rini
We move the spl_nand_load_image function to common/spl. This will allow for easier integration of SPL-boots-Linux code on other arches. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linuxTom Rini
In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer, clear the BSS and call board_init_r. We mark this as weak as some platforms may need to perform additional initalization at this point. We provide a gd that we know will be in a usable location, once the BSS has been cleared to help with this as well. Finally, we no longer call relocate_code so remove that from the armv7 version. Next, both board_init_f and jump_to_image_linux are going to be inherently arch-specific, so move these versions to arch/arm/lib/spl.c Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27SPL: Move the omap SPL framework to common/splTom Rini
Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series. We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27ARM: SPL: Move gpmc_init() to spl_board_init()Tom Rini
This is an OMAP/related-specific function, move calling it to spl_board_init() and turn on CONFIG_SPL_BOARD_INIT on the boards that enabled NAND and didn't enable this already. Signed-off-by: Tom Rini <trini@ti.com>

Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27ARM: SPL: Clean up spl.c / spl_nand.c slightlyTom Rini
- Remove includes we don't need - Switch some printf statements to puts - Convert some printf statements to debug, introduce new puts statements - In most cases saying just "No mkimage signature, assuming u-boot.bin" or similar is sufficient. This also means the non-DEBUG case doesn't need printf, in the core of SPL. - The other case here is that PLAIN_VERSION provided what we wanted already, so just use it. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27ARM: SPL: Make spl_mmc.c more genericTom Rini
Move the default omap/related-centric board_mmc_init to arch/arm/cpu/armv7/omap-common/boot-common.c and move the type defines to <asm/spl.h>. Also use mmc->read_bl_len rather than MMCSD_SECTOR_SIZE Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27ARM: SPL: Add <asm/spl.h> and <asm/arch/spl.h>Tom Rini
Move the SPL prototypes from <asm/omap_common.h> into <asm/spl.h> and add <asm/arch/spl.h> for arch specific portions of CONFIG_SPL_FRAMEWORK. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27ARM: SPL: Only call mem_malloc_init if configuredTom Rini
We can only attempt to setup a malloc pool if CONFIG_SYS_SPL_MALLOC_START is defined, and not all boards require it. Make the call depend on the define. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-27ARM: SPL: Remove NAND_MODE_HW_ECC from spl_nand.cTom Rini
This detection code doesn't (and can't) do anything currently, so remove. Signed-off-by: Tom Rini <trini@ti.com>

2012-09-10MX: set a common place to share code for Freescale i.MXStefano Babic
Up now only MX5 and MX6 can share code, because they have a common source directory in cpu/armv7. Other not armv7 i.MX can profit of the same shared code. Move these files into a directory accessible for all, similar to plat-mxc in linux. Signed-off-by: Stefano Babic <sbabic@denx.de>
2012-09-04am33xx: Remove redundant timer configTom Rini
We have the timer code in arch/arm/cpu/armv7/omap-common/timer.c that has been configuring and enabling the timer, so remove our code that does the same thing by different methods. Tested on EVM GP, SK-EVM and Beaglebone. Signed-off-by: Tom Rini <trini@ti.com>
2012-09-01mx5/6: Fix cpu_mmc_init() return valueBenoît Thébaudeau

2012-09-01mx5/6 timer: Round up tick_to_time() valueBenoît Thébaudeau
Round up tick_to_time() value instead of truncating it. This avoids stopping waits instantly for low usec values, and this generally guarantees that the code always waits for at least the requested duration.
