2012-07-21x86, boot: Exclude cmdline.c if you can't use itGokul Caushik1-2/+3
CONFIG_EARLY_PRINTK is the only feature that might use command line parsing in the decompression stage. If it is disabled then we can exclude the related code to save space. This can result in an estimated space savings of 2240 bytes from the compressed kernel image.

2012-07-21x86, boot: Exclude early_serial_console.c if can't use it.Joe Millenbach1-0/+10
Removes early_serial_console.c code if we don't have the config option that enables it (EARLY_PRINTK). When disabling this code, make early_serial_base a constant 0 to allow the compiler to optimize away the code that checks for early_serial_base.

2012-07-21x86, boot: Switch output functions from command-line flags to conditional ↵Joe Millenbach1-4/+13
compilation Changed putstr flagging from parameter to conditional compilation for puts, debug_putstr, and error_putstr. This allows for space savings since most configurations won't use this feature.

2012-07-21x86, boot: Changed error putstr path to match new debug_putstr formatJoe Millenbach1-0/+1
For consistency we changed the error output path to match the new debug path.

2010-08-02x86, setup: move isdigit.h to ctype.h, header files on top.H. Peter Anvin1-0/+1
It is a subset of <ctype.h> functionality, so name it ctype.h. Also, reorganize header files so #include statements are clustered near the top as they should be. Signed-off-by: H. Peter Anvin <[email protected]> LKML-Reference: <[email protected]>
2010-08-02x86, setup: enable early console output from the decompressorYinghai Lu1-0/+38
This enables the decompressor output to be seen on the serial console. Most of the code is shared with the regular boot code. We could add printf to the decompressor if needed, but currently there is no sufficiently compelling user. -v2: define BOOT_BOOT_H to avoid include boot.h -v3: early_serial_base need to be static in misc.c ? -v4: create seperate string.c printf.c cmdline.c early_serial_console.c after hpa's patch that allow global variables in compressed/misc stage -v5: remove printf.c related Signed-off-by: Yinghai Lu <[email protected]> Signed-off-by: H.
