Hopefully correct code for C's strict aliasing rules

1 # Makefile for bootrom, see ../common/Makefile.common for common settings

3 # DO NOT use thumb mode in the phase 1 bootloader since that generates a section with glue code
4 ARMSRC = fromflash.c
5 THUMBSRC = usb.c bootrom.c
6 ASMSRC = ram-reset.s flash-reset.s

8 ## There is a strange bug with the linker: Sometimes it will not emit the glue to call
9 ## BootROM from ARM mode. The symbol is emitted, but the section will be filled with
10 ## zeroes. As a temporary workaround, do not use thumb for the phase 2 bootloader
