* ARM: mach-omap1: clean up debug-macro.SNicolas Pitre2011-09-26
| | | | | | | | | | | | | | This achieves two goals: 1) Get rid of omap_uart_v2p() and omap_uart_p2v() which were the last users of PLAT_PHYS_OFFSET. 2) Remove the probing of the M bit in the CP15 control reg and make the access to the .data variables completely position independent.

| | | | | | | | | This is the first step to remove PLAT_PHYS_OFFSET usage from the debug UART code. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Tested-by: Tony Lindgren <tony@atomide.com> Reviewed-by: Kevin Hilman <khilman@ti.com>
* ARM: add an extra temp register to the low level debugging addruart macroNicolas Pitre2011-09-26
| | | | | | | | | | | | | Some platforms (like OMAP not to name it) are doing rather complicated hacks just to determine the base UART address to use. Let's give their addruart macro some slack by providing an extra work register which will allow for much needed cleanups. This is basically a no-op as this commit is only adding the extra argument to the macro but no one is using it yet.

| * ARM: 7012/1: Set proper TEXT_OFFSET for newer MSMsStephen Boyd2011-08-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MSMs post 8x50 have 2Mb at the beginning of RAM reserved for shared memory. Since the kernel hasn't typically been told this RAM exists, PHYS_OFFSET has been set to 0xN0200000 and the memory atags passed to the kernel have matched. This doesn't play nicely with things such as AUTO_ZRELADDR, which doesn't work at all, and dynamic phys to virt, which requires an MSM specific workaround. Work around these issues by telling the kernel RAM starts at 0xN0000000 (it actually does) and fixup the atags from the bootloader (if necessary) to say the same. In addition, make sure to set TEXT_OFFSET at least 2Mb beyond the start of RAM so that the kernel doesn't end up being decompressed into shared memory. After doing this, AUTO_ZRELADDR should work on MSM with no problems and ARM_PATCH_PHYS_VIRT_16BIT should no longer be necessary.

| | | | | | | | | | | | | | | | | | | | | | Enable virtual to physical translation patching by default in all kernels. Hide the option behind EMBEDDED. This can still be turned off if people desire, and they know what they're doing, to shrink the size of the kernel to a minimum.
