* | arm: move C runtime setup code in crt0.SAlbert ARIBAUD2013-01-08-0/+14
|/ | | | | | | | | | | | | | | | | | Move all the C runtime setup code from every start.S in arch/arm into arch/arm/lib/crt0.S. This covers the code sequence from setting up the initial stack to calling into board_init_r(). Also, rewrite the C runtime setup and make functions board_init_*() and relocate_code() behave according to normal C semantics (no jumping across the C stack any more, etc). Some SPL targets had to be touched because they use start.S explicitly or for some reason; the relevant maintainers and custodians are cc:ed. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

| * env: Add environment variable flagsJoe Hershberger2012-12-13-0/+4
| | | | | | | | | | | | | | | | | | | | | | Currently just validates variable types as decimal, hexidecimal, boolean, ip address, and mac address. If the entry is not found in the env ".flags", then look in the static one.

In some cases it can be avoided all together and at the least the code is only called from one place. Also name the function and the callback to more clearly describe what it does. Pass the ENTRY instead of just the name for direct access to the whole data structure. Pass an enum to the callback that specifies the operation being approved.

| * Add strcasecmp() and strncasecmp()Simon Glass2012-12-11-4/+12
| | | | | | | | | | | | | | | | | | | | | | strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space.

* lib/vsprintf.c: don't special-case pointers to address nullWolfgang Denk2012-11-02-0/+6
| | | | | | | | | | | | | | The %p format of printf() would print a pointer to address null as "(null)". This makes sense in a real OS where a NULL pointer must never be dereferenced, but this is a bootloader, and there are cases where accessing the data at address null makes perfect sense. Remove the special case in lib/vsprintf.c using "#if 0" with a comment to make clear this was an intentional change and to stop re-adding this code.

| * libfdt: Add helper function to create a trivial, empty treeGerald Van Baren2012-10-15-1/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The libfdt read/write functions are now usable enough that it's become a moderately common pattern to use them to build and manipulate a device tree from scratch. For example, we do so ourself in our rw_tree1 testcase, and qemu is starting to use this model when building device trees for some targets such as e500. However, the read/write functions require some sort of valid tree to begin with, so this necessitates either having a trivial canned dtb to begin with or, more commonly, creating an empty tree using the serial-write functions first. This patch adds a helper function which uses the serial-write functions to create a trivial, empty but complete and valid tree in a supplied buffer, ready for manipulation with the read/write functions.
