Blackfin: fix crash when booting from external memory

2009-04-02T10:41:56Z

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

Blackfin: put memory into self-refresh before/after programming clocks

2009-03-23T19:14:55Z

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

Blackfin: clarify relocation comment during init

2009-01-28T18:26:14Z

People often ask questions about the init process and when things go from flash to relocated base, so clarify the comments a bit. Signed-off-by: Mike Frysinger

Blackfin: just set SP register directly during init

2009-01-28T18:26:14Z

No need to set the SP register indirectly to the configured value when it can be set directly. Signed-off-by: Mike Frysinger

Blackfin: use common memcpy routine during init

2009-01-28T18:26:14Z

Rather than using a local custom memcpy function, just call the existing optimized Blackfin version. Signed-off-by: Mike Frysinger

Blackfin: small cpu init optimization while setting interrupt mask

2008-10-23T09:03:51Z

Use the sti instruction to set the initial interrupt mask rather than banging on the core IMASK MMR to save both space and time. Signed-off-by: Mike Frysinger

Blackfin: set initial stack correctly according to Blackfin ABI

Blackfin: enable support for nested interrupts

2008-10-23T09:03:50Z

During cpu init, make sure we initialize the CEC properly so that interrupts can fire and be handled while U-Boot is running. Signed-off-by: Mike Frysinger

rename CFG_ macros to CONFIG_SYS

Blackfin: unify cpu and boot modes

2008-03-30T19:50:19Z

All of the duplicated code for Blackfin processors and boot modes have been unified. After all, the core is the same for all processors, just the peripheral set differs (which gets handled in the drivers). Signed-off-by: Mike Frysinger
