| * 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: 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.

This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

* mx25: Fix eSDHC supportBenoît Thébaudeau2012-10-15-9/+10
| | | | | | | | | | | | | | | | The MMC driver appropriate for the i.MX25 is fsl_esdhc, which has nothing to do with mxcmmc. Also, each eSDHC instance has a dedicated clock, so gd->sdhc_clk must be set accordingly. This is good for the case only a single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).
