* env_callback.h: spl: mark callback as maybe_unusedJeroen Hofstee2014-07-181-1/+1
| | | | | | | | | | | | | When static inline is used in a header file the function should preferably be inlined and if not possible made a static function. When declared inside a c file there is a static function, which might be inlined. Since SPL uses a define to declare the static inline it becomes part of the c file although it is declared in a header and clang will warn that you have introduced unused static functions. Add maybe_unused to prevent such warnings. Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

* Refactor linker-generated arraysAlbert ARIBAUD2013-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

* lcd: implement a callback for splashimageNikita Kiryanov2013-03-111-0/+7
| | | | | | | | | | | | | On some architectures certain values of splashimage will lead to a data abort exception. Document the problem, and implement a callback for splashimage to reject such values.

* env: don't generate callback list entries for SPLScott Wood2012-12-221-0/+8
| | | | | | | | | | | | | | SPL doesn't write to the environment. These list entries prevent the functions from being garbage-collected, even though nothing will look at the list. This caused several SPL builds (e.g. P2020RDB-PC_NAND) to break due to size limitations and/or unresolved symbols. A static inline function is used to provide a context in which we can consume the callback, and thus avoid unused function warnings.

* env: Add environment variable flagsJoe Hershberger2012-12-131-0/+2
| | | | | | | | | | | 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. This allows the env to override the static definitions, but prevents the need to have every definition in the environment distracting you. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* env: Add a silent env handlerJoe Hershberger2012-12-131-0/+7
| | | | | | | | The silent variable now updates the global data flag anytime it is changed as well as after the env relocation (in case its value is different from the default env in such cases as NAND env) Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
