[LEDE-DEV] brcm47xx legacy broken in trunk?

[p.wassi at gmx.at]

Hi there!

I've just revived an old WRT54GL and implanted 32MB RAM into it - it works
perfectly well :)

However, for me, the latest working image seems to be 15.05.1.
I installed openwrt-15.05.1-brcm47xx-legacy-squashfs.trx which has kernel 3.18.23 and can
see this on the serial console during startup:
> (...)

However, if I take
  openwrt-brcm47xx-legacy-linksys-wrt54g-squashfs.bin, or
  lede-brcm47xx-legacy-linksys-wrt54g-squashfs.bin, or
  the trx versions of these for the sysupgrade, or
  the generic (and not legacy), just in case...
none of them work.
Serial console freezes at:

Maybe this is related to kernel switch 3.18.23 -> 4.1.x?
As the target images are still built, I guess support hasn't been dropped yet.
WRT54GL with 32MB: Er läuft und läuft und läuft... :)

Any thoughts on this?
