We haven't seen any use for the SPI API in McBSP driver over the years.

2011-06-29omap: cleanup NAND platform dataGrazvydas Ignotas6-23/+6
omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and 'dma_channel' are never referenced by the NAND driver, yet various board files are initializing those fields. This is both incorrect and confusing, so remove them. This allows to get rid of a global variable in gpmc-nand.c. This also corrects an issue where some boards are trying to pass NAND 16bit flag through .options, but the driver is using .devsize instead and ignoring .options. Finally, .dev_ready is treated as a flag by the driver, so make it bool instead of a function pointer.

2011-06-27omap2+: Rename timer-gp.c into timer.c to combine timer init functionsTony Lindgren2-3/+3
We can keep everything sys_timer and gptimer.c related code in timer.c as the code will be very minimal. Later on we can also remove timer-mpu.c, as it can be called from omap4_timer_init function. This allows us to get rid of confusing existing files. We currently have timer-gp.c, timer-mpu.c, and patches have been posted to add dmtimer.c. There's no need to have these multiple files, we can put everything into timer.c. Signed-off-by: Tony Lindgren <tony@atomide.com>

We will enable and disable interrupt on a need basis in the class driver. We need to keep the IRQ disabled by default else the forceupdate or vcbypass events could trigger events that we don't need/expect to handle. This is a preparation for SmartReflex AVS class drivers such as class 2 and class 1.5 which would need to use interrupts.

This is needed for the following patches so we can initialize the rest of the hardware timers later on. As with the init_irq calls, there's no need to do cpu_is_omap calls during the timer init as we only care about the major omap generation. This means that we can initialize the sys_timer with the .timer entries alone. Note that for now we just set stubs for the various sys_timer entries that will get populated in a later patch. The following patches will also remove the omap_dm_timer_init calls and change the init for the rest of the hardware timers to happen with an arch_initcall.

2011-06-09exec: delay address limit change until point of no returnMathias Krause2-2/+0
Unconditionally changing the address limit to USER_DS and not restoring it to its old value in the error path is wrong because it prevents us using kernel memory on repeated calls to this function. This, in fact, breaks the fallback of hard coded paths to the init program from being ever successful if the first candidate fails to load. With this patch applied switching to USER_DS is delayed until the point of no return is reached which makes it possible to have a multi-arch rootfs with one arch specific init binary for each of the (hard coded) probed paths. Since the address limit is already set to USER_DS when start_thread() will be invoked, this redundancy can be safely removed.

2011-06-09powerpc: Force page alignment for initrd reserved memoryBenjamin Herrenschmidt4-32/+43
When using 64K pages with a separate cpio rootfs, U-Boot will align the rootfs on a 4K page boundary. When the memory is reserved, and subsequent early memblock_alloc is called, it will allocate memory between the 64K page alignment and reserved memory. When the reserved memory is subsequently freed, it is done so by pages, causing the early memblock_alloc requests to be re-used, which in my case, caused the device-tree to be clobbered. This patch forces the reserved memory for initrd to be kernel page aligned, and will move the device tree if it overlaps with the range extension of initrd. This patch will also consolidate the identical function free_initrd_mem() from mm/init_32.c, init_64.c to mm/mem.c, and adds the same range extension when freeing initrd. free_initrd_mem() is also moved to the __init section. Many thanks to Milton Miller for his input on this patch.
