2009-05-07[ARM] S3C64XX: Add S3C6400 CPU detection.Ben Dooks
Add detection support for the S3C6400 SoC which has it's id register in a different place to the S3C6410. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C6400: Core support for S3C6400 SoCBen Dooks
Add the core support files for the Samsung S3C6400 SoC. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] SMDK6400: Initial machine support for SMDK6400Ben Dooks
Add minimial support for the SMDK6400 board to test the S3C6400 support. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] VIC: Add power management deviceBen Dooks
Add power management support to the VIC by registering each VIC as a system device to get suspend/resume events going. Since the VIC registeration is done early, we need to record the VICs in a static array which is used to add the system devices later once the initcalls are run. This means there is now a configuration value for the number of VICs in the system. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C: GPIO PM core GPIOlib integrationBen Dooks
Move the GPIO suspend/resume support inline with the gpiolib support so that it will work with both the S3C24XX and S3C64XX series. The s3c_gpio_chip is extended to have a pm callback and a save block to keep the state of the GPIO over suspend, and the code from the s3c24xx implementation is added to a new common file. The suspend process now uses the list of registered chips to go through saving and restoring each one as appropriate, using the pm callback to select the appropriate routine depending on the type of control register present. This change also means that any additional GPIO added should not require changes to the PM. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Add IRQ PM codeBen Dooks
Add support for saving the state of the IRQ registers over suspend. This requires moving the S3C64XX UART registers into <plat/regs-serial.h> and adding irq-pm.c which saves the state of all the IRQ registers. The irq-pm.c saves all the IRQ registers, including the IRQ_EINT and IRQ_EINT_GROUP registers as it was easier than adding three different files. Also ensuring that all the registers are restored to the same state as before suspend is considered to be the best thing to do. Note, we do not suspend the VIC here, this is done by the VIC driver itself. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Add generic s3c64xx sys device.Ben Dooks
Add an s3c64xx_sysclass and device for items that currently want to bind to any s3c64xx processor. The first user of this will be parts of the s3c64xx suspend support which need to save device state over suspend/resume. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Add s3c6410_sysclass exportBen Dooks
Add definition for s3c6410_sysclass which was missing from arch/arm/plat-s3c/include/plat/cpu.h. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C64XX: Initial support for PM (suspend to RAM)Ben Dooks
Add the initial support for the S3C64XX based systems to use suspend-to-RAM to sleep. Includes basic debugging for use with the SMDK6410 usign the LEDs on the baseboard. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C: PM save UART UDIVSLOT if doing PMBen Dooks
Add the facility to save the UART UDIVSLOT register if the UART state is being saved over suspend. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
2009-05-07[ARM] S3C: Add debug to UART save and a per-arch callback pre-restoreBen Dooks
Add a simple debug message on saving the UART state and add a per-arch pre-restore function to be used by the s3c64xx restore code to ensure the UARTs control registers do not go through any illegal state changes. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

2009-05-07[ARM] S3C: Rename S3C24XX_PA_USBHOST to S3C_PA_USBHOSTBen Dooks

2009-04-28powerpc: Revert switch to TEXT_TEXT in linker scriptTim Abbott
Commit edada399 broke the build on 64-bit powerpc because it moved the __ftr_alt_* sections of a file away from the .text section, causing link failures due to relative conditional branch targets being too far away from the branch instructions. This happens on pretty much all 64-bit powerpc configs. This change reverts commit edada399 while preserving the update from the *.refok sections to .ref.text that has happened since.

2009-04-28powerpc/cell: Select PCI for IBM_CELL_BLADE AND CELLEBMichael Ellerman
Currently PPC_CELL_NATIVE selects PPC_OF_PLATFORM_PCI, but does not select PCI. This can lead to a config with the former and the latter disabled, which does not build. To fix this PPC_CELL_NATIVE should select PCI. However, that would force PCI on for QPACE, which also selects PPC_CELL_NATIVE. So instead move the select of PPC_OF_PLATFORM_PCI and PCI under both IBM_CELL_BLADE and CELLEB.

2009-04-28powerpc: ppc32 needs elf_read_implies_exec()Kumar Gala
On ppc64 we implemented elf_read_implies_exec() for 32-bit binaries because old toolchains had bugs where they didn't mark program segments executable that needed to be. For some reason we didn't do this on ppc32 builds. This hadn't been an issue until commit 8d30c14c ("powerpc/mm: Rework I$/D$ coherency (v3)"), which had as a side effect that we are now enforcing execute permissions to some extent on 32-bit 4xx and Book E processors. This fixes it by defining elf_read_implies_exec on 32-bit to turn on the read-implies-exec behaviour on programs that are sufficiently old that they don't have a PT_GNU_STACK program header.

Stop gcc from generating uninitialised variable warnings after BUG(). The problem is that FRV's call into its gdbstub appears to return (if the function is marked noreturn, then the compiler is under no obligation to pass it a return address, and so GDB won't know where the bug happened). To get around this, we make the do...while wrapper in _debug_bug_trap() an endless loop from which there's no escape.
