Crashes rarely happen in the CPLB miss handler compared to the rest of
U-Boot code, so disable hardware tracing when processing misses. This
way a crash due to other functions will be shown properly.

The single initcode function was growing unwieldy, so split it up the
distinct steps into their own function. This should making digesting the

While the initdram() function makes sense on some arches, it doesn't for

Very little additional code overhead, and only works when the user sets an
env var ahead of time, so default to on makes sense.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
The tinyboards like to run at a little lower voltage than the default, and
they prefer to boot over the network. For the latter, extend the common
code a little to make this easier.
Also fix the cm-bf527 env sector size while we're in here to reflect the
flash that is actually in use.

Adds required definitions for EHCI support in sequoia configuration file.
But still keeps the OHCI as default driver.
Signed-off-by: Chris Zhang <chris@seamicro.com>
In USB ehci driver, the port reset is not terminated. EHCI spec says "A host
controller must terminate the reset and stabilize the state of the port within
2 milliseconds". Without termination, a port stays at reset state. This is
observed on ppc4xx(sequoia) boards.

The RX Control/Status register has bits that we want to preserve, so don't
just write out a single bit. Preserve the others bits in the process.
The original code posted to the u-boot list had this behavior, but looks
like it was lost somewhere along the way to merging.

The dynamic FIFO handling under MUSB is optional, and some parts (like

Due to this, the FIFO reading/writing steps need special handling, so
mark the common versions weak so drivers can override.
