altos/stm: Align 'data' to 8 bytes, just like textram

2017-12-12T23:31:27+00:00

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. Signed-off-by: Keith Packard

If you try this after the UART is running, it won't work. Signed-off-by: Keith Packard
