2011-07-17arm: add CONFIG_MACH_TYPE setting and documentationIgor Grinberg
CONFIG_MACH_TYPE is used to set the machine type number in the common arm code instead of setting it in the board code. Boards with dynamically discoverable machine types can still set the machine type number in the board code. Signed-off-by: Igor Grinberg <grinberg@compulab.co.il>

2011-07-12Blackfin: switch to common display_options()Mike Frysinger
Use common code to output the version string rather than doing it ourselves. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: serial: move early debug strings into .rodata sectionMike Frysinger
Rewrite the assembly serial_early_puts() helper to place the strings in the .rodata section rather than embedding them directly in the .text section. Using .text is a little simpler, but it doesn't let people execute out of internal L1 sram (since core reads don't work on those regions). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-07-12Blackfin: serial: convert to bfin_{read,write} helpersMike Frysinger
Since the serial struct declares the sizes for us, no need to hardcode them in the accessor functions. Let the bfin_{read,write} helpers do it for us. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: split out async setupMike Frysinger
We really only need to tweak the async banks in the initcode if the processor is booting out of it, otherwise we can wait until later on in the CPU booting setup. This also makes testing in the sim and early bring up over JTAG work much smoother when the initcode gets bypassed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-07-12Blackfin: gpio: optimize free path a littleMike Frysinger
When we aren't doing resource tracking, the gpio_free() function is a stub that simply returns, so pull this logic up a level and make it an inline stub in the header. Now we don't have to waste time at any of the call sites. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: post: setup default CONFIG_SYS_POST_WORD_ADDRMike Frysinger
Set the default post word location to an L1 data location for all Blackfin parts so things "just work" for most people. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: uart: fix printf warningMike Frysinger
The code uses %i to printf a size_t when it should use %zu, otherwise we get a warning from gcc about it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: add init.elf helper codeMike Frysinger
This creates a standalone ELF that executes just the Blackfin initcode. This is useful for people who want to program the low level aspects of the CPU (memory/clocks/etc...) and can easily be used with JTAG for quick booting while developing. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: dont reset SWRST on newer bf526 partsMike Frysinger
The bug in the BF526 rom when doing a software reset exists only in older silicon versions, so don't clear SWRST on newer parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: uart: add multiple serial supportMike Frysinger
This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs. Ends up adding only ~512bytes per additional UART. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-12Blackfin: uart: move debug buffers into local bssMike Frysinger
There's no need for these saved buffers to be global symbols, or in the data section. So mark them static to move them into the bss. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-07-11powerpc/85xx: remove SERDES4 soft-reset work-aroundTimur Tabi
Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a bank soft-reset after the bank was configured and enabled, even though enabling a bank causes it to reset. Because the reset was required for multiple errata, it was not properly enclosed in an #ifdef, and so was not removed with all the other rev1 errata work-arounds. Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if bank 2 is enabled, but this was not being done for SERDES protocols 0xF and 0x10. The bank reset also happened to enable bank 3 (apparently an undocumented feature). Simply removing the reset breaks these two protocols. It turns out that every time we call enable_bank(), we do want at least one lane of the bank enabled, either because the bank is supposed to be enabled, or because we need the clock from that bank enabled. For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we call enable_bank(), because that array is used elsewhere to determine if the bank is available. Note that the side effect of these changes is that the work-arounds for these two errata are now linked. Specifically, if SERDES-A001 is enabled, then we need SERDES-8 enabled as well. Because this was the only SERDES bank soft-reset, there is no need to implement a work-around for erratum SERDES-A003. Also fix an off-by-one error in a printf().

On a 8308 based board it was found that the PEX_GLK_RATIO register (programmed in arch/powerpc/cpu/mpc83xx/pcie.c) was getting set to 0, This was tracked to the fact that the pci express clock frequency was not being assigned to the pciexp1_clk entry in the global data structure in file arch/powerpc/cpu/mpc83xx/speed.c.
