* arm: Use common .lds file where possibleSimon Glass2012-03-30-1071/+0
| | | | | | | | | | Each cpu directory currently has its own .lds file. This is only needed in most cases because the start.o file is in a different subdir. Now that we can factor out this difference, we can move most cpus over to the common .lds file. Signed-off-by: Simon Glass <sjg@chromium.org>
* arm: add a common .lds link scriptSimon Glass2012-03-30-0/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most ARM CPUs use a very similar link script. This adds a basic script that can be used by most CPUs. Two new symbols are introduced which are intended to eventually be defined on all architectures to make things easier for generic relocation and reduce special-case code for each architecture: __image_copy_start is the start of the text area (equivalent to the existing _start on ARM). It marks the start of the region which must be copied to a new location during relocation. This symbol is called __text_start on x86 and microblaze. __image_copy_end is the end of the region which must be copied to a new location during relocation. It is normally equal to the start of the BSS region, but this can vary in some cases (SPL?). Making this an explicit symbol on its own removes any ambiguity and permits common code to always do the right thing. This new script makes use of CPUDIR, now defined by both Makefile and spl/Makefile, to find the directory containing the start.o object file, which is always placed first in the image. To permit MMU setup prior to relocation (as used by pxa) we add an area to the link script which contains space for this. This is taken from commit 7f4cfcf. CPUs can put the contents in there using their start.S file. BTW, shouldn't that area be 16KB-aligned? Signed-off-by: Simon Glass <sjg@chromium.org>

* mx53: Make PLL2 to be the parent of UART clockFabio Estevam2012-03-27-3/+17
| | | | | | | | | | | | | | | | | | Change the parent UART clock to be PLL2, so that U-boot can also boot a Freescale 2.6.35 kernel for mx53. FSL kernel and U-boot changed the UART parent from PLL3 to PLL2 to avoid conflicts with IPU clocks, so that the video resolution can be changed without affecting the UART clock. On a 2.6.35 kernel the serial console is messed up after IPU driver is loaded and this patch fixes this problem. Tested on a mx53loco board booting a FSL kernel and also a mainline kernel.

* armv7: omap3: leave outer cache enabledAneesh V2012-02-27-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Mainline kernel for OMAP3 doesn't enable L2 cache It expects L2$ to be enabled by ROM-code/bootloader. Leaving L2$ enabled can be troublesome in cases where the L2 cache is not under CP15 control, such as in Cortex-A9. This problem is explained in detail in the commit dc7100f4080952798413fb63bb4134b22c57623a However, this problem doesn't apply to Cortex-A8 because L2$ in Cortex-A8 is under CP15 control and hence the generic armv7 maintenance opertions work for it. As such we can make an exception for OMAP3 and leave the L2$ enabled when we jump to kernel. This is done by removing the strongly-linked implementation of v7_outer_cache_disable() and allowing it to fall back to the weakly linked implementation that doesn't do anything.

The substantial difference between the davinci_dm6467evm and the davinci_dm6467Tevm configuration is a single bit in the hardware revision that is passed to the Linux kernel and davinci_dm6467evm has REFCLK_FREQ = 27000000 where as davinci_dm6467Tevm.h has a REFCLK_FREQ = 33000000. This patch removes include/configs/davinci_dm6467Tevm.h. Instead the include/configs/davinci_dm6467evm.h configuration is used for DM6467T EVMs and renamed CFG_REFCLK_FREQ to CONFIG_REFCLK_FREQ and CONFIG_REFCLK_FREQ is defined in boards.cfg.
