linux.git/arch/c6x/kernel/head.S, branch v3.10 Linux kernel source tree C6X: early boot code 2011-10-06T23:47:28+00:00 Aurelien Jacquiot a-jacquiot@ti.com 2011-10-04T15:00:02+00:00 c1a144d77a6ca3a14ba3c0fec30bc4fd20b3d817 Original port to early 2.6 kernel using TI COFF toolchain. Brought up to date by Mark Salter <msalter@redhat.com> This patch provides the early boot code for C6X architecture. There is a 16 entry vector table which is used to direct reset and interrupt events. The vector table entries contain a small amount of code (maximum of 8 opcodes) which simply branches to the actual event handling code. The head.S code simply clears BSS, setups up a few control registers, and calls machine_init followed by start_kernel. The machine_init code in setup.c does the early flat tree parsing (memory, commandline, etc). At setup_arch time, the code does the usual memory setup and minimally scans the devicetree for any needed information.

Original port to early 2.6 kernel using TI COFF toolchain.

This patch provides the early boot code for C6X architecture. There is a
16 entry vector table which is used to direct reset and interrupt events. The
vector table entries contain a small amount of code (maximum of 8 opcodes)
which simply branches to the actual event handling code.

The head.S code simply clears BSS, setups up a few control registers, and calls
machine_init followed by start_kernel. The machine_init code in setup.c does
the early flat tree parsing (memory, commandline, etc). At setup_arch time, the
code does the usual memory setup and minimally scans the devicetree for any
needed information.
