2013-04-28mx23: Put back RAM voltage level to its original valueFabio Estevam
commit 5c2f444c9 (mxs: Reset the EMI block on mx23) changed the DDR voltage level, which causes mx23evk to fail to load a kernel. Put back the original values, so that mx23evk can boot a kernel again. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Tested-by: Robert Nelson <robertcnelson@gmail.com>
2013-04-26mx53ard: Rework default environment to support FDT, MMC and netbootOtavio Salvador

2013-04-26mxs: mxsboot: Move sdcard BCB header to 4 sectors offsetOtavio Salvador
The MX23 Boot ROM does blindly load from 2048 offset while the MX28 does parse the BCB header to known where to load the image from. We move the BCB header to 4 sectors offset so same code can be used by both SoCs avoiding code duplication.

2013-04-25mx51evk: Do not force the rootfs typeFabio Estevam
Currently mmcrootfstype is set to ext3 type. It is better not to force it in the env vars, because users may prefer a different file system type, so let's get rid of 'mmcrootfstype'. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Otavio Salvador <otavio@ossystems.com.br>
2013-04-25mx51evk: Update environment in order to allow booting a dt kernelFabio Estevam
Update the environment as done in other imx boards to allow easy switching between booting a non-dt kernel and a dt kernel. Change CONFIG_LOADADDR to 0x92000000, so that we can have the: - uImage at 0x92000000 - imx51-babbage.dtb at 0x91000000 ,which are adequate locations in RAM to avoid overlapping.

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."

2013-04-25imx: mx6q_4x_mt41j128.cfg: Setup CCM_CCOSR registerFabio Estevam
Setup CCM_CCOSR register to provide a CKO1 clock frequency of 16.5 MHz. CKO1 drives sgtl5000 codec clock on mx6qsabrelite and 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. mx6q_4x_mt41j128.cfg is also used by mx6qsabresd, and it is safe to use it for this board as well.

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.

2013-04-17ARM: mx6: define CONFIG_ARM_ERRATA_742230Shawn Guo
The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is claimed for Cortex-A9 (r1p0..r2p2). Though i.MX6 uses a newer revision than r2p2, we are seeing a reboot failure on i.MX6 SMP build that can be fixed by applying the workaround for this errata. So for safety, let's define CONFIG_ARM_ERRATA_742230 to enable the workaround on i.MX6. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
