* mxs: Add MX23 quirks into the clock codeOtavio Salvador2013-01-21-9/+26
| | | | | | | | | | The MX23 has different handling of the SSP clock and GPMI NAND clock sources, add necessary quirks into the clock code to properly handle these.

* mxs: Fix the memory init for MX23Otavio Salvador2013-01-21-15/+78
| | | | | | | | | | The memory init is slightly different on MX23, thus split the memory init for mx23 and mx28 into different functions.

* mxs: ssp: Pull out the SSP bus to regs conversionMarek Vasut2013-01-21-1/+1
| | | | | | | | | | | | | Create function which converts SSP bus number to SSP register pointer. This functionality is reimplemented multiple times in the code, thus make one common implementation. Moreover, make it a switch(), since the SSP ports are not mapped in such nice linear fashion on MX23, therefore having it a switch will simplify things there.

* pxa: Save lr register in relocate_code functionŁukasz Dałek2013-01-14-0/+2
| | | | | | | | | | | When u-boot is compiled for PXA25x processor, pxa/start.S is calling cpu_init_crit by BL instruction. BL is overwriting lr register so relocate_code is going into infinite loop. This patch preservs lr register in r12 before calling cpu_init_crit and after function returns restores it. Signed-off-by: Lukasz Dalek <luk0104@gmail.com> Acked-by: Marek Vasut <marex@denx.de>

| * mx6: Add workaround for ARM errataFabio Estevam2013-01-09-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add workaround for the following ARM errata: 743622 and 751472. The motivation for this change is the following kernel commit 62e4d357a (ARM: 7609/1: disable errata work-arounds which access secure registers), which removes the errata from multiplatform kernel. Since imx has been converted to multiplatform in the kernel, we need to apply such workarounds into the bootloader. Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel. Explanation of each erratum is provided at "Chip Errata for the i.MX 6Dual/6Quad" document available at: cache.freescale.com/files/32bit/doc/errata/IMX6DQCE.pdf Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
