[ros-diffs] [ros-arm-bringup] 32136: On ARM, it seems first = "true" parsing doesn't actually work in .rbuild files -- the object is not properly placed in the beginning of the FreeLDR text section. As a workaround, a special "startup" section is now used to contain the boot.s code, and a linker flag is used to set this section as the entrypoint section at 0x8000. FreeLDR for ARM now links properly, with _start at 0x8000.

Log:
On ARM, it seems first = "true" parsing doesn't actually work in .rbuild files -- the object is not properly placed in the beginning of the FreeLDR text section.
As a workaround, a special "startup" section is now used to contain the boot.s code, and a linker flag is used to set this section as the entrypoint section at 0x8000.
FreeLDR for ARM now links properly, with _start at 0x8000.
