[U-Boot] [PATCH v3 0/2] fdt: Deal correctly with alias nodes

[Simon Glass]

This series proposes a new way to deal with alias nodes and introduces a
function to take care of it.

Drivers can now request an ordered list of compatible nodes in a single
step. This simplifies node discovery for drivers (and keeps this nasty
code in a common place).

If DEBUG is defined the alias function will print messages in the event
of a warning/error.

Changes in v2:
- Add test_fdtdec command to test fdtdec_find_aliases_for_id()
- Allow gaps in the list returned to the caller
- Improve alias checking algorithm to reduce run time
- Rename function to fdtdec_find_aliases_for_id()
- Skip nodes marked as disabled

Changes in v3:
- Change 'continue' to 'break' in last loop, since we are done anyway
- Change fdtdec-test.c to fdtdec_test.c to fit better with U-Boot conventions
- Fix typos and add two assert() checks
- Remove varargs declaration (hang-over from previous implementation)
- Use COMPAT_UNKNOWN instead of COMPAT_NVIDIA_TEGRA20_I2C for test
