altos: Speed up at45 and 25lc erase speeds

2011-01-08T01:54:54+00:00

No need to read the block to be erased before erasing it. Signed-off-by: Keith Packard

altos: Move common storage code to ao_storage.c. Add M25P80 driver

2011-01-07T06:37:38+00:00

This reworks the storage API so that you erase blocks and then store data to them so that the M25P80 driver will work. Signed-off-by: Keith Packard

altos: Require manual flight erasing.

2011-01-07T01:34:58+00:00

This supports flash chips that require larger erase blocks. Signed-off-by: Keith Packard

altos: Simplify storage API

2011-01-06T20:51:39+00:00

This removes the config-specific APIs and exposes global variables for the available storage space, block size and config storage location. Signed-off-by: Keith Packard

altos: Split out SPI driver.

2010-12-23T05:17:36+00:00

For TM with the companion connector, the SPI bus will be shared among multiple devices. Split out the existing SPI code into a common driver, with the SPI bus protected by a mutex. Signed-off-by: Keith Packard

Save some DSEG space by marking cmd functions __reentrant

2009-10-16T03:56:45+00:00

__reentrant causes the compiler to place args and locals on the stack instead of in the data segment. Signed-off-by: Keith Packard

Make eeprom reads and writes across block boundary work

2009-09-03T04:57:54+00:00

Reading and writing across the block boundary was not stepping the eeprom position after the partial i/o operation at the end of the first block. This meant that the operation would re-use the end of the previous block, either re-reading or re-writing it. Signed-off-by: Keith Packard

Use autotools, move altos to src subdir
