2010-10-07x86: Change compiler optionsGraeme Russ
Change to: - reparam=3 - no-from-pointer - no-stack-protector - preferred-stack-boundary=2 - no-top-level-reorder These options make the code a little smaller and faster
2010-10-07x86: Coding Style CleanupGraeme Russ
Perform some basic code cleanups of the x86 files
2010-10-07x86: Move loading of GTD to C codeGraeme Russ
Linux has C macros and code to load the GTD after switching to Protected Mode. Using these greatly simplifies the assembler code
2010-10-07x86: use gc sections to reduce image sizeGraeme Russ
Follow the discussion of Charles Manning and Mike Frysinger. Using gc_sections helps reduce image size.
2010-10-07x86: zboot updateGraeme Russ
The header of recent Linux Kernels includes the size of the image, and therefore is not needed to be passed to zboot. Still process the third parameter (size of image) in the event that an older kernel is being loaded
2010-10-07x86: Make CONFIG_RELOC_FIXUP_WORKS generic for all x86 boardsGraeme Russ
Relocation is not board-specific for the x86 architectrure, so CONFIG_RELOC_FIXUP_WORKS can be defined globally in the config.h

2010-10-06PCU_E: remove code for yet another corpseWolfgang Denk
The PCU_E board has long reached EOL, and support for it is no longer relevant in current versions of U-Boot. Remove it. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-10-05at91: Add arch_preboot_os which disables PIT in a faster wayAlexander Stein
When disabled the PIT runs until it reaches the CPIV value. The Linux PIT driver stops the PIT and waits until it stopped. This can take over 100ms. Simply stopping in u-boot isn't sufficient as the PIT will still be running when Linux is waiting until it stopped. So, we stop it in u-boot by setting the compare value to a value slightly greater than the current running counter to make the PIT stopped in short time.

2010-10-04ppc4xx: Remove some testing hacks from ppc4xx.hStefan Roese
I accidentally left these hacks in the code while doing the big header cleanup. Let's remove it now. Signed-off-by: Stefan Roese <sr@denx.de>

2010-10-04APM821xx: Add CPU supportTirumala Marri
APM821XX is a new line of SoCs which are derivatives of PPC44X family of processors. This patch adds support of CPU, cache, tlb, 32k ocm, bootstraps, PLB and AHB bus. Signed-off-by: Tirumala R Marri <tmarri@apm.com> Signed-off-by: Stefan Roese <sr@denx.de>

Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: propagate target cpu defines when building embedded envMike Frysinger
Since we're no longer extracting the env from the target ELF file (since upstream wouldn't take that change), we're back to the problem of cpu defines not properly propagating to the env setup stage. So the embedded env built by the host compiler doesn't match the one that is linked into the u-boot env. Reported-by: Vivi Li <vivi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: cmd_gpio: accept upper case pin namesMike Frysinger
The intention all along was to accept pin names irrelevant of their case. But I guess I forgot to test/implement support for that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: cmd_gpio: return gpio value to callerMike Frysinger
Make the GPIO command usable in a scripting environment by returning the GPIO value rather than always 0. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: cmd_gpio: document/extend input sub-optionMike Frysinger
The input sub command was missing from the help text, and it didn't show the actual value currently read on the GPIO. This allows people to read the value of input pins. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: move CONFIG_BFIN_CPU to board config.mkMike Frysinger
The CONFIG_BFIN_CPU option is largely used in the build system, so move it out of the board config.h and into the board config.mk. It'd be nice to keep everything in the config.h, but the patch to extract that value early was rejected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: bf561: merge headersMike Frysinger
Only the BF561 port was using the common dual core headers, so merge them into the BF561 specific headers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: bf533: merge headersMike Frysinger
Only the BF533 port was using the common extended headers, so merge them into the BF533 specific headers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-10-02Blackfin: punt headers for non-existent BF541Mike Frysinger
There is no BF541 processor variant, so punt headers for it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-10-02Blackfin: bfin_spi: add optional DMA supportMike Frysinger
This moves the last piece from the old spi_flash driver to the new SPI framework -- optional DMA RX support. This typically cuts speeds by ~40% at the cost of additional ~300 bytes. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2010-09-29MX51: Added pins definition to set up padsStefano Babic

2010-09-29ARM: Use syslib functions for all CORTEXA8Stefano Babic
The OMAP3 cpu directory contains a syslib file with some utilities that can be shared by all targets using arm cortexa8 processors, not only OMAP. Signed-off-by: Stefano Babic <sbabic@denx.de>
2010-09-29Use common function to set GPIOs for MX3 and MX5Stefano Babic
The patch adds support for setting gpios to the MX51 processor and change name to the corresponding functions for MX31. In this way, it is possible to get rid of nasty #ifdef switches related to the processor type. Signed-off-by: Stefano Babic <sbabic@denx.de>

2010-09-28mpc512x: fix build issuesWolfgang Denk
Commit 800eb0964 "POST cleanup." removed file arch/powerpc/cpu/mpc512x/common.c but failed to remove the reference to it from arch/powerpc/cpu/mpc512x/Makefile which causes somewhat obscure build errors: make[1]: *** No rule to make target `/work/wd/tmp-ppc/arch/powerpc/cpu/mpc512x/.depend', needed by `_depend'.

2010-09-28ARMV7: OMAP4: Calculate SDRAM sizeAneesh V

2010-09-2383xx: Remove warmboot parameter from PCI init functionsPeter Tyser
This change lays the groundwork for the BOOTFLAG_* flags being removed. This change has the small affect of delaying 100ms on PCI initialization after a warm boot as opposed to the optimal 1ms on some boards.

2010-09-23mpc83xx/pcie: make it compile with PCIE2 unconfiguredIlya Yanok

2010-09-23ppc4xx: Disable trace broadcast for 44x non debug modeVictor Gallardo
By default the trace broadcast is enabled on 44x systems. To reduce power consumption when instruction tracing is not needed, disable trace broadcast. Check External Debug Mode (EDM) bit to detect if it should be disabled or not. Resetting system via a debugger will set the DBCR0[EDM] bit. Resetting via u-boot or OS will not.

2010-09-23ppc4xx: Cleanup of PVR detection code in cpu.cStefan Roese
This patch cleans the PVR detection code in check_cpu() up a bit. Basically the strings are better seperated, resulting in an easier to understand and maintain code version. The #ifdef's couldn't be removed easily because of two reasons: - Some SoC revisions have the same PVR, so need a way to differentiate between those two SoC's. - In some case statements registers only available in this SoC variant are referenced. Instead I moved the CONFIG_440 #ifdef a bit, so that 405 platforms don't add this 440 detection code and vice versa. Resulting in this U-Boot image size change: 405EX (Kilauea): 408 bytes less 440EPx (Sequoia): 604 bytes less 460EX (Canyonlands): 564 bytes less Signed-off-by: Stefan Roese <sr@denx.de> Cc: Wolfgang Denk <wd@denx.de>
2010-09-23Remove unused CONFIG_SERIAL_SOFTWARE_FIFO featureStefan Roese
This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO feature from U-Boot. It has only been implemented for PPC4xx and was not used at all. So let's remove it and make the code smaller and cleaner. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
