Otherwise we could end up trying to build files before the links

Let's use a heavy handed approach and not build *anything* until

The write(2) system call returns the number of bytes written, this is
important since it is entitled to write less than what we requested.
Currently we ignore the return value and assume it wrote everything we
requested. While in practice this is likely to always be the case, it
isn't actually correct.
This patch addresses this.

This patch adds support to handle OCC load/start event from FSP/PRD.
During IPL we send a success directly to FSP without invoking any HBRT
load routines on recieving OCC load mbox message from FSP. At runtime
we forward this event to host opal-prd.
This patch provides support for invoking OCC load/start HBRT routines
like load_pm_complex() and start_pm_complex() from opal-prd.

Add the misc flag clear_on_ecc_error to libflash/pflash. This was

When performing a read the return value from pflash is non-zero, even for
a successful read, when the size being read is not a multiple of 256.
This is because do_read_file returns the value from the write system
call which is then returned by pflash. When the size is a multiple of
256 we get lucky in that this wraps around back to zero. However for any
other value the return code is size % 256. This means even when the
operation is successful the return code will seem to reflect an error.
Fix this by returning zero if the entire size was read correctly,
otherwise return the corresponding error code.

Currently we assume that this tool is being used on a P8 system by
default and allow the user to override this behaviour using the -8 and
-9 command line arguments. When running on the host we can use the
PVR to guess what chip generation so do that.
This also changes the default behaviour to assume that the host is a P9
when running on an ARM system. This tool didn't even work when compiled
for ARM until recently and the OpenBMC vPNOR hack that we have currently
is broken for P9 systems that don't use vPNOR (Zaius and Romulus).

It is possible to erase within a single erase block. Currently the
pflash code assumes that if the erase starts part way into an erase
block it is because it needs to be aligned up to the boundary with the
next erase block.
Doing an erase smaller than a single erase block will cause underflows
and looping forever on erase.

Add a new sub-command that allows us to create GARD records for
arbitrary chip units. There isn't a whole lot of constraints on this and
that limits how useful it can be, but it does allow a user to GARD out
individual DIMMs, chips or cores from the BMC (or host) if needed.
There are a few caveats though:
1) Not everything can, or should, have a GARD record applied it to.
2) There is no validation that the unit actually exists. Doing that
sort of validation requires something that understands the FAPI
targeting information (I think) and adding support for it here
would require some knowledge from the system XML file.
3) There's no way to get a list of paths in the system.
4) Although we can create a GARD record at runtime it won't be applied
until the next IPL.

The output of `gard list` has a field named "Type", however this
doesn't actually indicate the type of the record. Rather, it
shows the type of the path used to identify the hardware being
GARDed. This is of pretty dubious value considering the Physical

Source the list of units from the hostboot source rather than the
previous hard coded list. The list of path element types changes
between generations so we need to add a level of indirection to

When using the current implementation of the gard tool to ecc clear the
entire GUARD partition it is done one gard record at a time. While this
may be ok when accessing the actual flash this is very slow when done
from the host over the mbox protocol (on the order of 4 minutes) because
the bmc side is required to do many read, erase, writes under the hood.
Fix this by rewriting the gard tool reset_partition() function. Now we
allocate all the erased guard entries and (if required) apply ecc to the
entire buffer. Then we can do one big erase and write of the entire
partition. This reduces the time to clear the guard partition to on the
order of 4 seconds.

The erase_range() function handles erasing the flash for a given start
address and length, and can handle an unaligned start address and
length. However in the unaligned start address case we are incorrectly
calculating the remaining size which can lead to incomplete erases.
If we're going to update the remaining size based on what the start
address was then we probably want to do that before we overide the
origin start address. So rearrange the code so that this is indeed the
case.

This adds a program that can be run inside a mambo simulator in linux
userspace which enables TCP sockets to be proxied in and out of the
simulator to the host.
Unlike mambo bogusnet, it's requires no linux or skiboot specific
drivers/infrastructure to run.
eg.
Run inside the simulator:
- to forward host ssh connections to sim ssh server
./mambo-socket-proxy -h 10022 -s 22
Then connect to port 10022 on your host
ssh -p 10022 localhost
- to allow http proxy access from inside the sim to local http proxy
./mambo-socket-proxy -b proxy.mynetwork -h 3128 -s 3128
Multiple connections are supported.
