Blackfin: use on-chip reset func with newer parts

2011-06-03T17:26:45Z

Turns out the documentation is wrong and doing "RAISE 1" does not result in a software reset, only a core reset. So when the on-chip rom has a functioning reset helper, use it. Signed-off-by: Mike Frysinger

Blackfin: use common LDSCRIPT logic

2011-06-03T17:26:45Z

Now that common code is a bit smarter when it comes to default LDSCRIPT values, rename the default Blackfin file and drop the Blackfin-specific config.mk logic. Signed-off-by: Mike Frysinger

gpio: generalize for all generic gpio providers

2011-04-13T19:56:51Z

The Blackfin gpio command isn't terribly Blackfin-specific. So generalize the few pieces into two new optional helpers: name_to_gpio() - turn a string name into a GPIO # gpio_status() - display current pin bindings (think /proc/gpio) Once these pieces are pulled out, we can relocate the cmd_gpio.c into the common directory.

Make STANDALONE_LOAD_ADDR configurable per board

2011-04-12T20:58:32Z

Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR and allow that the architecture-specific default value gets overwritten by defining the value in the board header file.

Blackfin: replace "bfin_reset_or_hang()" with "panic()"

2011-04-08T04:44:27Z

The bfin_reset_or_hang function unnecessarily duplicates the panic() logic based on CONFIG_PANIC_HANG. This patch deletes 20 lines of code and just calls panic() instead. This also makes the following generic-restart conversion patch simpler. Signed-off-by: Kyle Moffett Signed-off-by: Mike Frysinger

Blackfin: bootrom.h: sync with toolchain

2011-04-08T04:44:27Z

We need the updated LDR bit defines for our LDR utils. Signed-off-by: Mike Frysinger

Blackfin: default to L1 bank A when L1 bank B does not exist

2011-04-08T04:44:26Z

Some parts lack Bank B in L1 data, so have the linker script fall back to Bank A when that happens. This way we can still leverage L1 data. Signed-off-by: Mike Frysinger

Blackfin: turn off caches when self initializing

2011-04-08T04:44:26Z

When bootstrapping ourselves on the fly at runtime (via "go"), we need to turn off the caches to avoid taking software exceptions. Since caches need CPLBs and CPLBs need exception handlers, but we're about to rewrite the code in memory where those exception handlers live, we need to turn off caches first. This new code also encourages a slight code optimization by storing the MMR bases in dedicated registers so we don't have to fully load up the pointer regs multiple times.

Blackfin: only check for os log when we have external memory

2011-04-08T04:44:26Z

If the part has no external memory configured, then there will be no os log for us to check, and any attempt to access that memory will trigger hardware errors. Signed-off-by: Mike Frysinger
