2013-01-14pxa: Save lr register in relocate_code functionŁukasz Dałek
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>

2013-01-09mx6: Add workaround for ARM errataFabio Estevam
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>

2013-01-09kirkwood: make MPP arrays static constAlbert ARIBAUD
This saves stack and code memory for local copy, and consumes initialized data memory. For 22 of the 29 kirkwood-based boards, this results in a global saving of about 30 bytes. For 7 of them, it results in an increase of 6 to 14 bytes. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
2013-01-08arm: remove useless code in start.S filesAlbert ARIBAUD
Remove code such as unneeded includes or labels. These removals have no functional effect. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
2013-01-08arm: move C runtime setup code in crt0.SAlbert ARIBAUD
Move all the C runtime setup code from every start.S in arch/arm into arch/arm/lib/crt0.S. 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>

2012-12-11mxs: i2c: Implement algorithm to set up arbitrary i2c speedMarek Vasut
This algorithm computes the values of TIMING{0,1,2} registers for the MX28 I2C block. This algorithm was derived by using a scope, but the result seems correct. The resulting values programmed into the registers do not correlate with the contents in datasheet. When using the values from the datasheet, the I2C clock were completely wrong.

2012-12-10Pass sdrc timing values through board_sdrc_timings structurePeter Barada
Instead of passing individual registers by value to board_get_mem_timings, pass a board_mem_timings structure pointer for the board files to fill in. Pass same structure pointer to write_sdrc_timings. This saves about 90 bytes of space in SPL. Signed-off-by: Peter Barada <peter.barada@logicpd.com>

Implement common function to setup the VDDIO, VDDD and VDDA voltage. Right now, there are two almost identical functions to setup VDDIO and VDDD, which is prone to breakage. Pull out the differences into constant structure and pass them as an argument to the common function. Moreover, the function has almost identical loops for setting higher and lower VDDx voltage.

2012-11-19arm: Add control over cachability of memory regionsSimon Glass
Add support for adjusting the L1 cache behavior by updating the MMU configuration. The mmu_set_region_dcache_behaviour() function allows drivers to make these changes after the MMU is set up. It is implemented only for ARMv7 at present. This is needed for LCD support, where we want to make the LCD frame buffer write-through (or off) rather than write-back.
