New Revision: 1701
URL: http://flashrom.org/trac/flashrom/changeset/1701
Log:
uintptr_t-ify map_flash_region functions.
unsigned long is not the right type for manipulating pointer values.
Since C99 there are suitable unsigned and signed types available, namely
uintptr_t and intptr_t respectively.
Use them in functions assigned to programmers' map_flash_region fields and
their callers where applicable.
This patch also changes the display width of all associated address values in
physmap.c to 16/8 hex characters depending on the actual size by
introducing a macro PRIxPTR_WIDTH and exploiting printf's * field width
specifier.
