* x86: use gc sections to reduce image sizeGraeme Russ2010-10-07-0/+3
| | | | | Follow the discussion of Charles Manning and Mike Frysinger. Using gc_sections helps reduce image size.
* x86: zboot updateGraeme Russ2010-10-07-5/+13
| | | | | | 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
* x86: Make CONFIG_RELOC_FIXUP_WORKS generic for all x86 boardsGraeme Russ2010-10-07-0/+2
| | | | | Relocation is not board-specific for the x86 architectrure, so CONFIG_RELOC_FIXUP_WORKS can be defined globally in the config.h

| * Blackfin: propagate target cpu defines when building embedded envMike Frysinger2010-10-02-0/+3
| | | | | | | | | | | | | | | | | | | | | | 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>
| * Blackfin: cmd_gpio: accept upper case pin namesMike Frysinger2010-10-02-2/+3
| | | | | | | | | | | | | | 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>
| * Blackfin: cmd_gpio: return gpio value to callerMike Frysinger2010-10-02-1/+1

| * Blackfin: cmd_gpio: document/extend input sub-optionMike Frysinger2010-10-02-14/+13
| | | | | | | | | | | | | | | | 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>
| * Blackfin: move CONFIG_BFIN_CPU to board config.mkMike Frysinger2010-10-02-9/+2
| | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | This change lays the groundwork for the BOOTFLAG_* flags being removed.

| * ppc4xx: Disable trace broadcast for 44x non debug modeVictor Gallardo2010-09-23-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Victor Gallardo <vgallardo@apm.com> Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Cleanup of PVR detection code in cpu.cStefan Roese2010-09-23-71/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * Remove unused CONFIG_SERIAL_SOFTWARE_FIFO featureStefan Roese2010-09-23-22/+0
| | | | | | | | | | | | | | | | | | 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>
| * ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-716/+242
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Big header cleanup part 2, mostly PPC405 relatedStefan Roese2010-09-23-845/+610
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. As a part from this cleanup, the GPIO definitions for PPC405EP are corrected. The high and low parts of the registers (for example CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in the wrong order. This patch now fixes this issue by switching these xxxH and xxxL values. This brings the GPIO 405EP port in sync with all other PPC4xx ports. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | This patch starts a bit PPC4xx header cleanup. First patch mostly touches PPC440 files. A later patch will touch the PPC405 files as well. This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. Signed-off-by: Stefan Roese <sr@denx.de>
