The PIOE device was left out before because it muxes SDRAM pins (and is therefore a bit dangerous to mess with) and because no existing drivers had any use for it. It is needed for CompactFlash, however, and now that we have a way to protect the SDRAM pins, it can be safely added. Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

Bugfixes for external irq handler set_irq_type(): - If set_irq_type() can't set the type, don't change anything! - It's not OK to change the flow handler as part of set_irq_type(), among other issues that violates spinlock rules. Instead, we can call the relevant handler when we demux the external interrupts. - The external irq demux has no need to grab the spinlock. And in fact grabbing it that way was wrong, since that code might be pre-empted by an irq at a different priority level, and that code might then have tried to grab that spinlock...

This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

The macb driver will probe for the PHY chip and read the mac address from the MACB registers, so we don't need them in eth_platform_data anymore. Since u-boot doesn't currently initialize the MACB registers with the mac addresses, the tag parsing code is kept but instead of sticking the information into eth_platform_data, it uses it to initialize the MACB registers (in case the boot loader didn't do it.) This code should be unnecessary at some point in the future. Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

While working on SH kprobes, I noticed that avr32 got the preemption handling wrong in the no probe case. The idea is that upon entry of kprobe_handler() preemption is disabled outright across the life of the kprobe, only to be re-enabled in post_kprobe_handler(). However, in the event that the probe is never activated, there's never any chance of hitting the post probe handler, which allows for the current avr32 implementation to disable preemption indefinitely, as it's currently missing a re-enable when no probe is activated.

board_early_init() is left over from some early prototyping work where we had to initialize the SDRAM controller ourselves. This depends on the kernel being loaded into static RAM, which just isn't possible on any commercially available products today. In order to run without a boot loader, we need to create a zImage stub or have the debugger initialize the SDRAM for us (for really low-level debugging) Signed-off-by: NHaavard Skinnemoen <hskinnemoen@atmel.com>

The read[bwl] and write[bwl] functions are meant for accessing PCI devices. How this is achieved on AVR32 is unknown, as there are no systems with a PCI bridge available yet. On-chip peripheral access, however, should not depend on how we end up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl] is the right thing to do for on-chip peripherals. This patch converts the drivers for the static memory controller, interrupt controller, PIO controller and system manager to use __raw MMIO access.

Allow the board to remap actual USART peripheral devices to serial devices by calling at32_map_usart(hw_id, serial_line). This ensures that even though ATSTK1002 uses USART1 as the first serial port, it will still have a ttyS0 device. This also adds a board-specific early setup hook and moves the at32_setup_serial_console() call there from the platform code.

In order to initialize the serial console early, the atmel_serial driver had to do a hack where it compared the physical address of the port with an address known to be permanently mapped, and used it as a virtual address. This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.
