c6x: remove architecture

2021-01-20T08:30:45Z

The c6x architecture was added to the kernel in 2011 at a time when running Linux on DSPs was widely seen as the logical evolution. It appears the trend has gone back to running Linux on Arm based SoCs with DSP, using a better supported software ecosystem, and having better real-time behavior for the DSP code. An example of this is TI's own Keystone2 platform. The upstream kernel port appears to no longer have any users. Mark Salter remained avaialable to review patches, but mentioned that he no longer has access to working hardware himself. Without any users, it's best to just remove the code completely to reduce the work for cross-architecture code changes. Many thanks to Mark for maintaining the code for the past ten years.

c6x: include: asm: setup: Include "linux/types.h"

2015-03-26T14:39:46Z

Some modules may assume "asm/setup.h" already include all headers which needed by itself. So need let "asm/setup.h" include "linux/types.h", the related error: C [M] drivers/input/joydev.o In file included from include/asm-generic/page.h:23:0, from ./arch/c6x/include/asm/page.h:9, from include/asm-generic/io.h:14, from arch/c6x/include/generated/asm/io.h:1, from drivers/input/joydev.c:15: ./arch/c6x/include/asm/setup.h:17:27: error: unknown type name 'phys_addr_t' extern int c6x_add_memory(phys_addr_t start, unsigned long size); ^ Signed-off-by: Chen Gang Signed-off-by: Mark Salter

c6x: use boot_command_line instead of private c6x_command_line

2013-10-09T16:37:27Z

Save some pointless copying of the kernel command line and just use boot_command_line instead. Also remove default_command_line as it is not referenced anywhere, and the DT code already handles the default command line.

c6x: remove internal kernel symbols from exported setup.h

Some internal kernel symbols were referenced in the exported setup.h. This splits out the internal bits from the exported uapi bits. Signed-off-by: Mark Salter
