2013-04-25wandboard: Add card detection for SOM MicroSD cardOtavio Salvador
This add support to identify if the card is connected or not; so it does not try to communicate with the controller if no card is available. Signed-off-by: Otavio Salvador <otavio@ossystems.com.br>
2013-04-25nitrogen6x: Setup CCM_CCOSR registerFabio Estevam
CKO1 drives sgtl5000 codec clock on nitrogen boards and wandboard. Doing this setup in the bootloader will allow us to remove a lot of code in arch/arm/mach-imx/mach-imx6q.c from the mainline kernel. Also, according to Eric Nelson: "enabling the clock <in the bootloader> will remove squeal after an ungraceful reboot (watchdog) if hooked up to speakers."

2013-04-22imx: Move some i.MX common functions into the imx-common directoryStefan Roese
This patch moves the following functions into the imx-common directory: - mxs_wait_mask_set() - mxs_wait_mask_clr() - mxs_reset_block() These are currently used by i.MX28. But the upcoming GPMI NAND port for i.MX6 will also use these functions. So lets move them to a common location to re-use them.

The following headers are moved to a i.MX common location: - regs-common.h - regs-apbh.h - regs-bch.h - regs-gpmi.h - dma.h This way this header can be re-used also by other i.MX platforms. For example the i.MX6 which will need it for the upcoming NAND support.

2013-04-15Tegra: Split tegra_get_chip_type() into soc & sku funcsTom Warren
As suggested by Stephen Warren, use tegra_get_chip() to return the pure CHIPID for a Tegra SoC (i.e. 0x20 for Tegra20, 0x30 for Tegra30, etc.) and rename tegra_get_chip_type() to reflect its true function, i.e. tegra_get_chip_sku(), which returns an ID like TEGRA_SOC_T25, TEGRA_SOC_T33, etc. Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>

2013-04-15Tegra: Restore cp15 VBAR _start vector write for ARMv7Tom Warren
A start vector fix was added by AneeshV for OMAP4 (commit 0d479b53), and caused the old monilithic Tegra builds to hang due to an undefined instruction trap. Previously, the code needed to run on both the AVP (ARM7TDI) and A9, and the AVP doesn't have a CP15 register. I corrected this in commit 6d6c0bae w/#ifndef CONFIG_TEGRA, but now that we use SPL, and boot the AVP w/o any ARMv7 code, I can revert my change, and make Aneesh's change apply to Tegra.

2013-04-15ARM: tegra: support T33 SKU of Tegra30Stephen Warren
Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically to any other Tegra30. An alternative would be to simply remove the SKU checking from tegra_get_chip_type(); most use of the value most likely simply wants to know the current chip, not the specific SKU. Or, the function could be split into separate tegra_get_chip() and tegra_get_sku() for the cases where differentiation really is required. I wonder whether tegra_get_chip_type() should printf() whenever any unkown chip/SKU is found, although perhaps the function is called so early that the printf() wouldn't actually make it to the UART anyway.

2013-04-15ARMv7: start.S: stay in HYP mode if u-boot is entered in itAndre Przywara
The KVM and Xen hypervisors for the Cortex-A15 virtualization implementation need to be entered in HYP mode. Should the primary board firmware already enter HYP mode (Calxeda firmware does that), we should not deliberately drop back to SVC mode. Since U-boot does not use the MMU, running in HYP mode is just fine. Signed-off-by: Andre Przywara <andre.przywara@linaro.org>
2013-04-14ARM: fix CONFIG_SPL_MAX_SIZE semanticsAlbert ARIBAUD
Remove SPL-related ASSERT() in arch/arm/cpu/u-boot.lds as this file is never used for SPL builds. Rewrite the ASSERT() in arch/arm/cpu/u-boot-spl.lds to separately test image (text,data,rodata...) size, BSS size, and full footprint each against its own max, and make Tegra boards check full footprint. Also, output section mmutable is not used in SPL builds. Remove it. Finally, update README regarding the (now homogeneous) semantics of CONFIG_SPL_[BSS_]MAX_SIZE and add the new CONFIG_SPL_MAX_FOOTPRINT macro.

Commit 3ebd1cbc introduced compiler-generated __bss_start and __bss_end__ and commit c23561e7 rewrote all __bss_end__ as __bss_end. Their merge caused silent and harmless but potentially bug-inducing clashes between compiler- and linker- generated __bss_end symbols.

2013-04-13spi: mxc_spi: Set master mode for all channelsFabio Estevam
The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi clock glitch durant reset) solved, is back now and itwas re-introduced by commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling). Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function. Since the spi driver only supports master mode, set the mode for all channels always to master mode in order to have a stable, "glitch-free" SPI clock line.

When swi instruction is executed, it is expected to get message "software interrupt" in console and dump registers and reboot, as do_software_interrupt() in arch/arm/lib/interrupts.c. But, actually it causes data abort accessing wrong address in get_bad_stack_swi macro in arch/arm/cpu/v7/start.S. This patch fixes this problem.

2013-04-12imx: Add u-boot-with-nand-spl.imx make targetBenoît Thébaudeau
This image combines the SPL with the i.MX header, the FCB and U-Boot. For i.MX25/35/51, the FCB is ignored by the boot ROM, so this image is just useful because it can be programmed on a NAND Flash page boundary. For i.MX53, the FCB is required by the boot ROM. This does not support i.MX6 so far because its FCB is more complicated. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>

Some combinations were missing. At the same time, fix the build of SPL targets not supporting the imx header on arm1136.

2013-04-12arm: relocate_code(): Use __image_copy_end for end of relocationBenoît Thébaudeau

This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).
