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.

Git commit d417d1db5f9092d125ddea882ced77eaa5f3d236 replaced the omap-common file reset.S with reset.c, but the Makefile was not adjusted for that. Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca>

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: 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.

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.

2012-11-19mx5: Mark lowlevel_init board-specific codeBenoît Thébaudeau
The mx5 lowlevel_init.S contains board-specific code based on the reference design. Let's keep it since it avoids creating new lowlevel_init files and it may be used by many boards. But add a config to make it optional in order not to cause issues on boards not following this part of the reference design.

2012-11-04include/linux/byteorder: import latest endian definitions from linuxKim Phillips
u-boot's byteorder headers did not contain endianness attributions for use with sparse, causing a lot of false positives. Import the kernel's latest definitions, and enable them by including compiler.h and types.h. They come with 'const' added for some swab functions, so fix those up, too: include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default] Also, note: u-boot's historic __BYTE_ORDER definition has been preserved (for the time being at least). We also remove ad-hoc barrier() definitions, since we're including compiler.h in files that hadn't in the past: macb.c:54:0: warning: "barrier" redefined [enabled by default] In addition, including compiler.h in byteorder changes the 'noinline' definition to expand to __attribute__((noinline)).
