Designed around an ARM cortex A9 core, high-speed memory bus, advanced 3D accelerator and full-HD multi-format video decoder, SiRFprimaII is able to meet the needs of complicated applications for modern multifunction devices that require heavy concurrent applications and fluid user experience. Integrated with GPS baseband, analog and PMU, this new platform is designed to provide a cost effective solution for Automotive and Consumer markets. This patch adds the basic support for this SoC and EVB board based on device tree. It is following the ZYNQ of Xilinx in some degree.

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.

From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This usually means that no global variables can be marked static unless they're also const. To enforce this, suffice to fail the build whenever a private symbol is allocated to .bss and list those symbols for convenience. The user_stack and user_stack_end labels in head.S were converted into non exported symbols to remove false positives.

Turns out that this is unneeded as the size is already included at the end of the compressed piggy data. For those compressed formats that don't include this data, the build system already takes care of appending it using size_append in scripts/Makefile.lib. So let's use that instead.

Always bump the relocation address by the size of that code to avoid this issue. Noticed by Tony Lindgren <tony@atomide.com>. 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.

|/ | | | | | | | | | | | | | | | 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.

This guess may cause many issues by overestimating the final kernel image size: - This may force a needless relocation if the location of zImage was fine, wasting some precious microseconds of boot time. - The relocation may be located way too far, possibly overwriting the initrd image in RAM. - If the kernel image includes a large already-compressed initramfs image then the problem is even more exacerbated. And if by some strange means the 4x guess is too low then we may overwrite ourselves with the decompressed image. So let's use the exact decompressed kernel image size instead. For that we need to rely on the stat command, but this is hardly a new build dependency as the kernel already depends on many external commands to be built provided by the coreutils package where stat is found.

This would be more efficient to do this the other way around i.e. relocate the compressed data up front instead, resulting in a smaller copy. That also has the advantage of making the code smaller and more straight forward. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * | | ARM: 6663/1: make Thumb2 kernel entry point more similar to the ARM oneNicolas Pitre2011-02-231-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some installers would binary patch the kernel zImage to replace the first few nops with custom instructions. This breaks the Thumb2 kernel as the mode switch is right at the beginning. Let's move it towards the end of the nop sequence instead.

| * | | ARM: add 'uinstall' target for installing uboot kernelsRussell King2011-02-231-0/+4
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have 'install' and 'zinstall' for installing Image and zImage kernels, so add 'uinstall' to complete the set. This allows developers to have a ~/bin/installkernel script which (eg) copies the kernel to the tftp server automatically once the kernel has built, resulting in a better workflow.

| | | * ARM: 6597/1: Add basic architecture support for VIA/WonderMedia 85xx SoC'sAlexey Charkov2011-01-252-0/+50
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the family of Systems-on-Chip produced initially by VIA and now its subsidiary WonderMedia that have recently become widespread in lower-end Chinese ARM-based tablets and netbooks. Support is included for both VT8500 and WM8505, selectable by a configuration switch at kernel build time. Included are basic machine initialization files, register and interrupt definitions, support for the on-chip interrupt controller, high-precision OS timer, GPIO lines, necessary macros for early debug, pulse-width-modulated outputs control, as well as platform device configurations for the specific drivers implemented elsewhere.

| | * ARM: 6617/1: mmc, Add zboot from MMC support for SuperH Mobile ARMSimon Horman2011-01-253-1/+129
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows a ROM-able zImage to be written to MMC and for SuperH Mobile ARM to boot directly from the MMCIF hardware block. This is achieved by the MaskROM loading the first portion of the image into MERAM and then jumping to it. This portion contains loader code which copies the entire image to SDRAM and jumps to it. From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it. Cc: Magnus Damm <magnus.damm@gmail.com> Russell, please consider merging this for 2.6.38. This patch depends on: * "mmc, sh: Move MMCIF_PROGRESS_* into sh_mmcif.h" which will be merged though Paul Mundt's rmobile sh-2.6. The absence of this patch will break the build if the (new) CONFIG_ZBOOT_ROM_MMCIF option is set. There are no subtle side-effects. v2: Addressed comments by Magnus Damm * Fix copyright in vrl4.c * Fix use of #define CONFIG_ZBOOT_ROM_MMCIF in mmcif-sh7372.c * Initialise LED GPIO lines in head-ap4evb.txt instead of mmcif-sh7372.c as this is considered board-specific. v3: Addressed comments made in person by Magnus Damm * Move mmcif_loader to be earlier in the image and reduce the number of blocks of boot program loaded by the MaskRom from 40 to 8 accordingly. * Move LED GPIO initialisation into mmcif_progress_init - This leaves the partner jet script unbloated Other * inline mmcif_update_progress so it is a static inline in a header file v4: * Use htole16() and htole32() in v4rl.c to ensure that the output is little endian v5: Addressed comments by Russell King * Simplify assembly code * Jump to code rather than an address <- bug fix * Use (void __iomem *) as appropriate Roll in mackerel support * This was previously a separate patch, only because of the order in which this code was developed Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
