2013-01-09arch-kirkwood: Ethernet port macro returning incorrect addressLuke Lowrey
Modified the arch-kirkwood header so KWGBE_PORT_SERIAL_CONTROL1_REG(x) returns the correct address. Originally calling KWGBE_PORT_SERIAL_CONTROL1_REG(1) returned the address for port 0 and vice versa. Doesn't have any knock on effects to the u-boot code as the only time they're used is to do the same function to both addresses Signed-off-by: Luke Lowrey <luke@chamsys.co.uk> Acked-by: Prafulla Wadaskar <Prafulla@marvell.com> Acked-by: Heiko Schocher <hs@denx.de>
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>

2012-12-04mxs: Staticize SPL functionsMarek Vasut

2012-12-04mxs: Implement common function to setup VDDxMarek Vasut
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. Merge these two loops. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Stefano Babic <sbabic@denx.de> Cc: Fabio Estevam <fabio.estevam@freescale.com>
2012-12-04mx28: Rename regs-power.h to regs-power-mx28.hMarek Vasut
The i.MX23 has different register layout and bit placement in the power supply. Thus, in order to be able to add support for MX23, rename the MX28's regs-power.h to regs-power-mx28.h . Moreover, add ifdef around inclusion of regs-*-mx28.h in imx-regs.h so the MX23 boards will include proper set of registers.

2012-11-20musb-new: am35x backend driverIlya Yanok
Backend driver for MUSB OTG controllers found on TI AM35x. It seems that on AM35X interrupt status registers can be updated _before_ core registers. As we don't use true interrupts in U-Boot and poll interrupt status registers instead this can result in interrupt handler being called with non-updated core registers. This confuses the code and result in hanged transfers. Add a small delay in am35x_interrupt as a workaround. Signed-off-by: Ilya Yanok <ilya.yanok@cogentembedded.com>

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.

2012-11-19tegra: fdt: Add LCD definitions for TegraSimon Glass
Add LCD definitions and also a proposed binding for LCD displays. The PWM is as per what will likely be committed to linux-next soon. The displaymode binding comes from a proposal here: http://lists.freedesktop.org/archives/dri-devel/2012-July/024875.html The panel binding is new, and fills a need to specify the panel timings and other tegra-specific information. Should a binding appear that allows the pwm to handle this automatically, we can revisit this. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
2012-11-19tegra: fdt: Add pwm binding and nodeSimon Glass
