* gpio: Add support for microblaze xilinx GPIOMichal Simek2013-05-09-33/+7
| | | | | | | | | | | | | | | | | | | | | | | | Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <michal.simek@xilinx.com>

| * Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

* | Introduce generic link section.h symbol filesSimon Glass2013-03-15-0/+27
|/ | | | | | | | | | | | | | | | | | We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
