The console has already been initialized in the generic bootblock code, and
reinitializing it causes the same banner line to be printed twice and lots of
artifacts in the actual output. This same change had been made to the other
ARM boards but not for beaglebone.

These dependencies came indirectly through kconfig.h which was included
automatically with a -include option which was either part of INCLUDES or
specified directly. With this change, I'm able to build for beaglebone with

The way those variables work has changed twice since this file was last

For both romstage and ramstage, this calls an arch-specific function
get_cbmem_table() to resolve the base and size of CBMEM region. In ramstage,
the result is cached as the query may be relatively slow involving multiple PCI
configuration reads.
For x86 CBMEM tables are located right below top of low ram and
have fixed size of HIGH_MEMORY_SIZE in EARLY_CBMEM_INIT implementation.

Transaction consistently completes with 80 to 150 status reads on my

Timeout is set to DBGP_MICROFRAME_TIMEOUT_LOOPS=1000 status reads. Do not
retry transactions if this timeout is reached as the host controller
probably needs full re-initialisation to recover.
If this timeout is not reached, but a transaction is corrupted
on the wire, or it is otherwise not properly delivered to the USB device,
transaction is retried upto DBGP_MICROFRAME_RETRIES=10 times.

with simple device model. This will later allow to define PCI access
functions for ramstage using the inlined functions from romstage.

After an USB device sees USB bus reset on the bus, it will reset to
device number 0. Per the EHCI debug port specification, a debug
dongle device may reset to the fixed debug device number of 127 instead.
Thus there is no need to try device numbers from 1 to 126.
Do a sanity-check on a returned debug descriptor as I experienced
some USB flash memory to respond on this request with zero-fill data.

Resetting an EHCI controller when it is not halted can have
undefined behaviour. This mostly fixes a case where calling
usbdebug_init() twice would fail to reset the USB dongle device
properly.
On amd/persimmon it still requires one extra retry, but at least it
is now possible to have usbdebug enabled for both romstage and
ramstage.
