* Blackfin: bf537-stamp: bump default SCLK up to 125MHzMike Frysinger2009-03-24-1/+1
| | | | | | | Since all of the bf537-stamp and bf537-ezkit boards out there can handle it, increase the speed of SCLK to 125MHz rather than 100MHz. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf537-stamp: rewrite MAC-in-flash handlingMike Frysinger2009-03-24-23/+84
| | | | | | | Use the common net eth functions to setup the env/global data with the MAC address, and properly handle the case where CONFIG_SYS_NO_FLASH is defined. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: bf533-stamp: bump up default clocksMike Frysinger2009-03-24-1/+1
| | | | | | | Since the hardware can handle it, bump the default clocks from 80mhz SCLK and 398mhz CCLK to 100mhz SCLK and 498mhz CCLK. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf533-stamp: rewrite startup LED notificationsMike Frysinger2009-03-24-14/+73
| | | | | | | Again, don't clobber pins that we aren't actually using, and use the common LED framework rather than our own hob-job-but-not-really-working. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: unify common ADI board settingsMike Frysinger2009-03-24-937/+719
| | | | | | | | Rather than duplicate the same ADI settings in every ADI board, create a common ADI config header and have all ADI boards start using that. This will also make merging the ~10 boards I have to forward port a lot easier. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* 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
| | | | | | | Some newer Blackfins (like the BF51x) do not have an on-chip voltage regulator, so do not attempt to program the memory as if it does. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: setup a sane default EBIU_SDBCTL for SDRAM controllersMike Frysinger2009-03-23-0/+33
| | | | | | | If the board config does not specify an explicit EBIU_SDBCTL value, set it up with sane values based on other configuration options. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* 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: kill off LDR jump blockMike Frysinger2009-03-23-19/+14
| | | | | | | The Boot ROM uses EVT1 as the entry point so set that rather than having to use a tiny jump block in the default EVT1 location. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | The SPORT_TX registers cannot be read (the hardware will trigger an error), so drop the read helper macros. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: print out Flash: before checking itMike Frysinger2009-03-23-1/+1
| | | | | | | | If there is some problem in the flash init/checking code, it's nicer to see the message "Flash:" before crashing. This way the source of the problem is a bit more straightforward. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: spi: there is no PORTJ_FER MMR on BF537Sonic Zhang2009-03-23-5/+3
| | | | | | | | Since the PORTJ on the BF537 is peripheral-only (no GPIO functionality), then there is no PORTJ_FER register for us to worry about. Signed-off-by: Sonic Zhang <Sonic.Zhang@analog.com> 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the avr32-specific board_init_info hook by the standard board_early_init_r hook and make it optional. board_early_init_r() runs somewhat earlier than board_init_info used to do, but this isn't a problem for any of the in-tree boards.

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.

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.
