kconfig: fix trivial typos and update mconf documentation

2013-10-08T21:52:14+00:00

This fixes lots of typos in comments and strings. It also updates the documentation strings in mconf to reflect the changes in the user interface from the two commits 6364fd0cb1e4c7f72b974613e0cf5744ae4d2cb2 menuconfig: Add Save/Load buttons 1bdbac478a858d2aa73a6784c7c2e09de0f6d06b menuconfig: Get rid of the top-level entries for "Load an Alternate/Save an Alternate" And it updates the layout of the example search result, i. e. moves down the "Defined at" and "Depends on" lines and adds a symbol state ([=n]) to the symbol in the "Selected by" line. Furthermore, the help texts now should fit in 80 columns again when viewed in mconf. Signed-off-by: Martin Walch Reviewed-by: Jean Delvare Reviewed-by: Wang YanQing Signed-off-by: "Yann E. MORIN"

kconfig: switch to "long long" for sanity

2013-08-15T20:48:06+00:00

Instead of using "long" for kconfig "hex" and "range" values, which may change in size depending on the host architecture, use "long long". This will allow values greater than INT_MAX on 32-bit hosts when cross compiling. Signed-off-by: Kees Cook Acked-by: Geert Uytterhoeven Tested-by: "Yann E. MORIN" Signed-off-by: "Yann E. MORIN"

kconfig: simplify symbol-search code

2013-07-16T18:39:42+00:00

There is no need for a double indirection in the temporary array that stores the internediate search results. Reported-by: Jean Delvare Signed-off-by: "Yann E. MORIN" Reviewed-by: Jean Delvare

kconfig: don't allocate n+1 elements in temporary array

2013-07-16T18:36:18+00:00

The temporary array that stores the search results is not NULL-terminated, so there is no reason to allocate n+1 elements. Reported-by: Jean Delvare Signed-off-by: "Yann E. MORIN" Reviewed-by: Jean Delvare

kconfig: minor style fixes in symbol-search code

2013-07-16T18:34:44+00:00

Two minor style fixes: - no space before/after parenthesis in function definition - no {} for single-line if() And one grammar fix in a comment. Reported-by: Jean Delvare Signed-off-by: "Yann E. MORIN" Cc: Jean Delvare Reviewed-by: Jean Delvare

kconfig: avoid multiple calls to strlen

2013-07-16T18:26:46+00:00

Calls to strlen are costly, so avoid calling strln as much as we can. Reported-by: Jean Delvare Signed-off-by: "Yann E. MORIN" Cc: Jean Delvare Reviewed-by: Jean Delvare

kconfig: allow "hex" and "range" to support longs

2013-06-29T13:30:17+00:00

The parsing routines for Kconfig files use strtol(), but store and render values as int. Switch types and formating to long to support a wider range of values. For example, 0x80000000 wasn't representable. Signed-off-by: Kees Cook Tested-by: "Yann E. MORIN" Reviewed-by: "Yann E. MORIN" Signed-off-by: "Yann E. MORIN"

kconfig: sort found symbols by relevance

2013-06-24T17:57:45+00:00

When searching for symbols, return the symbols sorted by relevance. Sorting is done as thus: - first, symbols that match exactly - then, alphabetical sort Since the search can be a regexp, it is possible that more than one symbol matches exactly. In this case, we can't decide which to sort first, so we fallback to alphabeticall sort. Explain this (new!) sorting heuristic in the documentation. Reported-by: Jean Delvare Signed-off-by: "Yann E. MORIN" Cc: Jean Delvare Cc: Michal Marek Cc: Roland Eggner Cc: Wang YanQing -- Changes v1->v2: - drop the previous, complex heuristic in favour of a simpler heuristic that is both easier to understand, *and* to maintain (Jean) - explain sorting heuristic in the doc (Jean)

kconfig: Fix defconfig when one choice menu selects options that another choice menu depends on
