The purpose of this series is to improve and enhance the
handling of kernel boot arguments.
It is first focussed on powerpc but also extends the capability
for other arches.
This is based on suggestion from Daniel Walker <danielwa at cisco.com>
Main changes in V3:
- Also accept destination equal to source in cmdline_build() by setting a tmp buffer in __initdata. Powerpc provides different source and destination and call __cmdline_build() directly.
- Taken comments received from Will and Rob
- Converted all architectures (Only tested on powerpc)
Christophe Leroy (17):
cmdline: Add generic function to build command line.
drivers: of: use cmdline building function
cmdline: Gives architectures opportunity to use generically defined
boot cmdline manipulation
powerpc: Convert to GENERIC_CMDLINE
arm: Convert to GENERIC_CMDLINE
arm64: Convert to GENERIC_CMDLINE
hexagon: Convert to GENERIC_CMDLINE
microblaze: Convert to GENERIC_CMDLINE
nios2: Convert to GENERIC_CMDLINE
openrisc: Convert to GENERIC_CMDLINE
riscv: Convert to GENERIC_CMDLINE
sh: Convert to GENERIC_CMDLINE
sparc: Convert to GENERIC_CMDLINE
xtensa: Convert to GENERIC_CMDLINE
x86: Convert to GENERIC_CMDLINE
mips: Convert to GENERIC_CMDLINE
cmdline: Remove CONFIG_CMDLINE_EXTEND
