* mx5: Define a common get_board_rev()Fabio Estevam2013-04-25-0/+7
| | | | | | | | | | When booting a FSL kernel based on 2.6.35 it is necessary to pass the revision tag to the kernel. Place a common weak function into soc.c for such purpose. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Marek Vasut <marex@denx.de>
* mx51evk: Do not force the rootfs typeFabio Estevam2013-04-25-4/+2
| | | | | | | | | | 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'.

* mx51evk: Update environment in order to allow booting a dt kernelFabio Estevam2013-04-25-3/+39
| | | | | | | | | | | | | | | | | | | | | 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. Boot tested the following kernels: - 2.6.35 from FSL (11.09 branch) - 3.9-rc7 non-dt - 3.9-rc7 dt Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Otavio Salvador <otavio@ossystems.com.br>

* nitrogen6x: Setup CCM_CCOSR registerFabio Estevam2013-04-25-0/+12
| | | | | | | | | | | | 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."

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.

| | | | | | | | | | | | | | | | | | | | The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is claimed for Cortex-A9 (r1p0..r2p2).

| | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | | | | | | | | | | 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.
