| | | | | | | | | | | | | | | | | | | | | | | | | | | | AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed. The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board. It is essentially the same, with a few minor differences.

* | mpc5200: suppress printf until console initializedJon Smirl2009-03-25-10/+20
| | | | | | | | | | | | | | | | | | On boards which have the environment in eeprom, i2c_init() is called before the console and RAM are initialized. Suppress printfs until the console is initialized. Signed-off-by: Jon Smirl <jonsmirl@gmail.com> Acked-by: Heiko Schocher <hs@denx.de>
* | Blackfin: put memory into self-refresh before/after programming clocksMike Frysinger2009-03-23-82/+190
| | | | | | | | | | | | | | | | | | | | | | When initializing the core clocks, stick external memory into self-refresh. This gains us a few cool things: - support suspend-to-RAM with Linux - reprogram clocks automatically when doing "go" on u-boot.bin in RAM - make sure settings are stable before flashing new version - finally fully unify initialize startup code path between LDR/non-LDR Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: do not program voltage regulator on parts that do not have oneMike Frysinger2009-03-23-3/+20

* | Blackfin: handle reboot anomaly 432Mike Frysinger2009-03-23-0/+6
| | | | | | | | | | | | | | | | | | | | | | Workaround anomaly 432: The bfrom_SysControl() firmware function does not clear the SIC_IWR1 register before executing the PLL programming sequence. Therefore, any interrupt enabled in the SIC_IWR1 register prior to the call to bfrom_SysControl() can prematurely terminate the idle sequence required for the PLL to relock properly. SIC_IWR0 is properly handled. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* | Blackfin: fix jtag console tstcMike Frysinger2009-03-23-4/+11
| | | | | | | | | | | | | | | | | | | | The jtag tstc operation was checking the hardware to see if data is available from it (which is fine for the jtag getc operation), but the higher layers need to know whether any data is available. Since we have to read up to 4 bytes at a time from the hardware, the higher layers need to know they can consume the cached bytes as well. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | * | avr32: Add support for "GPIO" port muxHaavard Skinnemoen2008-09-01-0/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "GPIO" port mux is used on AVR32 UC3 parts as well as AT32AP7200 and all later AVR32 chips.

| | * | avr32: Use board_postclk_init instead of gclk_initHaavard Skinnemoen2008-09-01-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the avr32-specific gclk_init() board hook with the standard board_postclk_init() hook which is supposed to run at the same point during initialization. Provide a dummy weak alias for boards not implementing this hook. The cost of this is: - 2 bytes for the dummy function (retal 0) - 2 bytes for each unnecessary function call (short rcall) which is a pretty small price to pay for avoiding lots of #ifdef clutter. In this particular case, all boards probably end up slightly smaller because we avoid the conditional checking if the gclk_init symbol is NULL.

| | * | avr32: refactor the portmux/gpio codeHaavard Skinnemoen2008-09-01-317/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Separate the portmux configuration functionality from the GPIO pin control API. - Separate the controller-specific code from the chip-specific code. - Allow "ganged" port configuration (multiple pins at once). - Add more flexibility to the "canned" peripheral select functions: - Allow using more than 23 address bits, more chip selects, as well as NAND- and CF-specific pins. - Make the MACB SPEED pin optional, and choose between MII/RMII using a parameter instead of an #ifdef. - Make it possible to use other MMC slots than slot 0, and support different MMC/SDCard data bus widths. - Use more reasonable pull-up defaults; floating pins may consume a lot of power. - Get rid of some custom portmux code from the mimc200 board code. The old gpio/portmux API couldn't really handle its requirements, but the new one can. - Add documentation. The end result is slightly smaller code for all boards. Which isn't really the point, but at least it isn't any larger. This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if the board maintainers could help me test this on their boards. In particular, the mimc200 port has lost a lot of code, so I'm hoping Mark can help me out.

Separated functionality into separate CPU and Architecture components. It appears as if the i386 interrupt handler functionality was intended to allow multiple handlers to be installed for a given interrupt. Unfortunately, this functionality was not fully implemented and also had the problem that irq_free_handler() does not allow the passing of the handler function pointer and therefore could never be used to free specific handlers that had been installed for a given IRQ. There were also various issues with array bounds not being fully tested. I had two objectives in mind for the new implementation: 1) Keep the implementation as similar as possible to existing implementations. To that end, I have used the leon2/3 implementations as the reference 2) Seperate CPU and Architecture specific elements. All specific i386 interrupt functionality is now in cpu/i386/ with the high level API and architecture specific code in lib_i386. Functionality specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has been further split out into an individual file to allow for the implementation of the PIC architecture of the SC520 CPU (supports more IRQs) Signed-off-by: Graeme Russ <graeme.russ at gmail.com>

Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
