| * | | 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: 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OneNAND IPL has common codes for RAM init, load data, and jump to 2nd bootloader, but it's common code used about 300~400 bytes. So board specific codes, such as lowlevel_init, can't has enough code. It make a difficult to implement OneNAND IPL. his patch make this common code as small as possible. and give lowlevel_init can have more codes.

* | | Add wait flags to support board/chip specific delaysWolfgang Grandegger2009-03-23-11/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The corresponding Linux FSL UPM driver uses similar delay points at the same locations. To manage these extra delays in a more general way, I introduced the "wait_flags" field allowing the board-specific driver to specify various types of extra delay.

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.
