Can bootcode.bin pick up any parameters (other than noting the

No idea, but one problem I've had in the past is that USB devices can take a
while to initialise, and it varies quite a bit between devices.  This could
be a reason why boots will sometimes fail - especially with eg spinning HDD.

Often it was necessary to add an explicit delay so that system didn't try to
read them before they were ready.  I think on Linux the kernel cmdline
options were 'rootwait' and 'rootdelay' but I don't know if bootcode.bin has
any kind of setting like that.
