Menon, Nishanth b9655280e2 This is Kconfig cleanup patch (not all configurations will use CFI, SPI, RAMFS and DEVFS). 
* Enable CFI and SPI drivers menuconfig option to be able to disable them in menuconfig.
* Introduce capability to disable ramfs and devfs.

Sascha Hauer e77ed305e6 add missing null pointer check in unlink() 2008-03-01 21:05:23 +01:00
Carsten Schlote c1bba7e226 [general] Fixed crash in fs.h, when called with fsdrv.create == NULL 
When a nor0 devices has no partitions assigned, then a call to
open() to create a file will jump with a NULL fct ptr.

Much more cheching code is missing and pointers to function are
jumped without any NULL ptr check. This must be fixed as well later.

- do more POSIX:
  - use DIR instead of struct dirent
  - use (struct dirent)->d_name instead of (struct dirent)->name
- switch to a new layout for U_BOOT_CMD:
  - use C99 initializers to be able to add more fields to the
    command struct
  - add aliases for commands (needed mainly for help -> ? and test -> [
  - This is not done for all commands yet, but the compiler will tell you ;)
