https://git.ethernal.org/mjb/altos/atom?h=debian%2F1.8.7-22017-12-12T23:31:27+00:00altos/stm: Align 'data' to 8 bytes, just like textram2017-12-12T23:31:27+00:00Keith Packardkeithp@keithp.com2017-12-12T23:31:27+00:00urn:sha1:28dbe9a04b16f79db255baecbf0cd486c510ef58
The textram section must be aligned to 8 bytes to keep the linker
happy. However, if that section contains no data, the declaration will
set the __data_start__ value to that alignment, but the data section
itself would start on a 4-byte alignment, potentially 4 bytes lower
than the value indicated by __data_start__. This completely scrambles
initialized memory as the startup code will copy the data segment to
__data_start__, 4 bytes off of the actual data segment start.
Fix this by forcing the data segment to also be aligned to 8 bytes.

altos/stmf0: Fix linker scripts to make ao_boot work2015-01-27T06:10:47+00:00Keith Packardkeithp@keithp.com2015-01-27T06:10:47+00:00urn:sha1:e1d5bcb1968e280b8ebdf6c8b12e8a87167fd890
The flash loader ended up assuming ao_boot was at the start of ram,
while the application stuck it after the interrupt table (where it
needs to go).

altos: Add self-flash support for STM32F042 processor2015-01-26T03:35:19+00:00Keith Packardkeithp@keithp.com2015-01-26T03:35:19+00:00urn:sha1:df881bce8576f091b2d8cb53b8ce8a43aeedecde
Also moves the usual address for applications out of the way of the
flash loader.
