ARM: imx: cm_fx6: env: don't run boot scripts twice
Boot scripts located in the root directory of the first partition of
USB, mmc, and SATA drives are executed twice: first by the distro boot
command and then by the legacy boot command. This may have weird side
effects if those scripts only change or extend the environment
(including parts of the boot command itself).
Removing the script execution from the legacy boot command has its own
caveats. For instance, the distro boot command may execute the boot.scr
on the mmc drive, then the boot.scr on the SATA drive, before the
legacy boot command actually boots from the mmc drive. However, the
current behavior would only execute the boot.scr once more before the
actual boot, but it does not prevent the script located on the SATA
drive from being executed, and thus, both scripts from being mixed up.
Considering that the legacy boot command is only in place to boot old
(standard) installations, let's go with the resolution having less
custom code and remove the script execution from the legacy boot
command.

This patch is ported from the Linux patch posted at [1] and applied to
net tree as commit f1e2400a80ff.
The purpose of this change is to fix the incorrect detection of the link
partner (LP) advertised capabilities which sometimes happens with this PHY
(roughly 1 time in a dozen)
This issue may cause the link to be negotiated at 10Mbps/Full or
10Mbps/Half when 100MBps/Full is actually possible. In some case, the link
is even completely broken and no communication is possible.
To detect the corruption, we must look for a magic undocumented bit in the
WOL bank (hint given by the SoC vendor kernel) but this is not enough to
cover all cases. We also have to look at the LPA ack. If the LP supports
Aneg but did not ack our base code when aneg is completed, we assume
something went wrong.
The detection of a corrupted LPA triggers a restart of the aneg process.
This solves the problem but may take up to 6 retries to complete.
