2009-04-05mpc5200: reduce delays in i2cJon Smirl
The previous code waited 1000us before checking i2c status. Measurement shows i2c is usually ready in under 50us. Change the polling interval to 15us, loop 6,667 times to keep the polling timeout constant at 100ms.

2009-04-02Blackfin: fix crash when booting from external memoryMike Frysinger
When testing a u-boot binary that hasn't been booted from the bootrom, we have to make sure the bootstruct structure has sane storage space. If we don't, the initcode will crash when it tries to dereference an invalid pointer. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-04-0185xx: Introduce determine_mp_bootpg() helper.Kumar Gala
Match determine_mp_bootpg() that was added for 86xx. We need this to address a bug introduced in v2009.03 with 86xx MP booting. We have to make sure to reserve the region of memory used for the MP bootpg() so other u-boot code doesn't use it. Also added a comment about how cpu_reset() is dealing w/an errata on early 85xx MP HW. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-04-0186xx: Cleanup MP supportKumar Gala
* Use CONFIG_MP instead of CONFIG_NUM_CPUS to match 85xx * Introduce determine_mp_bootpg() helper. We'll need this to address a bug introduced in v2009.03 with 86xx MP booting. We have to make sure to reserve the region of memory used for the MP bootpg() so other u-boot code doesn't use it. * Added dummy versions of cpu_reset(), cpu_status() & cpu_release() to allow cmd_mp.c to build and work. In the future we should look at implementing all these functions. This could be common w/85xx if we use spin tables on 86xx. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-03-30MPC85xx: Add MPC8569 CPU supportHaiying Wang
There is a workaround for MPC8569 CPU Errata, which needs to set Bit 13 of LBCR in 4K bootpage. We setup a temp TLB for eLBC controller in bootpage, then invalidate it after LBCR bit 13 is set.

2009-03-25mpc5200: suppress printf until console initializedJon Smirl

2009-03-23Blackfin: put memory into self-refresh before/after programming clocksMike Frysinger
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>
2009-03-23Blackfin: do not program voltage regulator on parts that do not have oneMike Frysinger

2009-03-23Blackfin: setup a sane default EBIU_SDBCTL for SDRAM controllersMike Frysinger

2009-03-23Blackfin: handle reboot anomaly 432Mike Frysinger
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>
