2012-08-03ARM: dt: tegra: rename board files to match SoCStephen Warren
Most ARM ${board}.dts files are already named ${soc}-${board}.dts. This change modifies the Tegra board files to be named the same way for consistency. Once a related change is made in U-Boot, this will cause both U-Boot and the kernel to use the same names for the .dts files and SoC identifiers, thus allowing U-Boot's recently added "soc" and "board" environment variables to be used to construct the name of Tegra .dtb files, and hence allow board-generic U-Boot bootcmd scripts to be written.

2012-08-03ARM: zImage: allow supplementing appended DTB with traditional ATAG dataNicolas Pitre
Some old bootloaders can't be updated to a device tree capable one, yet they provide ATAGs with memory configuration, the ramdisk address, the kernel cmdline string, etc. To allow a device tree enabled kernel to be used with such bootloaders, it is necessary to convert those ATAGs into FDT properties and fold them into the DTB appended to zImage. Currently the following ATAGs are converted: ATAG_CMDLINE ATAG_MEM ATAG_INITRD2 If the corresponding information already exists in the appended DTB, it is replaced, otherwise the required node is created to hold it. The code looks for ATAGs at the location pointed by the value of r2 upon entry into the zImage code. If no ATAGs are found there, an attempt at finding ATAGs at the typical 0x100 offset from start of RAM is made. Otherwise the DTB is left unchanged.

The appended DTB gets relocated with the decompressor code to get out of the way of the decompressed kernel. However the kernel's .bss section may be larger than the relocated code and data, and then the DTB gets overwritten. Let's make sure the relocation takes care of moving zImage far enough so no such conflict with .bss occurs. Thanks to Tony Lindgren <tony@atomide.com> for figuring out this issue.

2011-07-19ARM: 6999/1: head, zImage: Always Enter the kernel in ARM stateDave Martin
Currently, the documented kernel entry requirements are not explicit about whether the kernel should be entered in ARM or Thumb, leading to an ambiguitity about how to enter Thumb-2 kernels. As a result, the kernel is reliant on the zImage decompressor to enter the kernel proper in the correct instruction set state. This patch changes the boot entry protocol for head.S and Image to be the same as for zImage: in all cases, the kernel is now entered in ARM. Documentation/arm/Booting is updated to reflect this new policy. A different rule will be needed for Cortex-M class CPUs as and when support for those lands in mainline, since these CPUs don't support the ARM instruction set at all: a note is added to the effect that the kernel must be entered in Thumb on such systems.

To be able to relocate the .bss section at run time independently from the rest of the code, we must make sure that no GOTOFF relocations are used with .bss symbols.

While at it, let's start the copy from the restart symbol which makes the above code size computation possible by the assembler directly (same sections), given that we don't need to preserve the code before that point anyway.

2011-03-28ARM: 6826/1: Merge v6 and v7 DEBUG_LL DCC supportStephen Boyd
The inline assembly differences for v6 vs. v7 are purely optimizations. On a v7 processor, an mrc with the pc sets the condition codes to the 28-31 bits of the register being read. It just so happens that the TX/RX full bits the DCC support code is testing for are high enough in the register to be put into the condition codes. On a v6 processor, this "feature" isn't implemented and thus we have to do the usual read, mask, test operations to check for TX/RX full. Thus, we can drop the v7 implementation and just use the v6 implementation for both.

2011-03-25mmc: Add MMC_PROGRESS_*Simon Horman
This is my second attempt to make this enum generally available. The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h. However this is not sufficiently generic as the enum will be used by SDHI boot code. Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-03-25mmc, ARM: Rename SuperH Mobile ARM zboot helpersSimon Horman
These headers and helpers will also be used for SDHI boot so the mmcif name will start to make a lot less sense. Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
