xtensa: implement ndelay

2014-01-14T20:28:11+00:00

Proper ndelay implementation allows for faster IO rate with drivers that use ndelay to access their device registers, as otherwise ndelay is emulated with udelay. Signed-off-by: Max Filippov

xtensa: clean up udelay

2014-01-14T20:28:10+00:00

Replace division with shift, use ccount_freq instead of loops_per_jiffy. Introduce __MAX_UDELAY and (undefined) __bad_udelay, break build for too big udelay constants. Remove irrelevant comment, clean up code style. Signed-off-by: Max Filippov

xtensa: fix __delay for small loop count

2014-01-14T18:19:53+00:00

Avoid __delay counter underflow for loop counts < 2. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: consolidate ccount access routines

2013-07-08T08:11:37+00:00

Use get_ccount everywhere; remove xtensa_get_ccount. Signed-off-by: Baruch Siach Signed-off-by: Chris Zankel

xtensa: clean up files to make them code-style compliant

2012-12-19T05:10:25+00:00

Remove heading and trailing spaces, trim trailing lines, and wrap lines that are longer than 80 characters. Signed-off-by: Chris Zankel

xtensa: reorganize SR referencing

2012-10-16T04:48:08+00:00

- reference SRs by names where possible, not by numbers; - get rid of __stringify around SR names where possible; - remove unneeded SR names from asm/regs.h; - add SREG_ prefix to remaining SR names; Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: move headers files to arch/xtensa/include

2008-11-06T18:25:09+00:00

Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.
