For a TPM device to be operational we need to initialize it and
perform its startup sequence. The 'tpm init' command currently calls
tpm_init() which ends up calling the ->open() per-device callback and
performs the initial hardware configuration as well as requesting
locality 0 for the caller. There no code that currently calls
tpm_init() without following up with a tpm_startup() and tpm_self_test_full()
or tpm_continue_self_test().
So let's add a 'tpm autostart' command and call tpm_auto_start() which
leaves the device in an operational state.
It's worth noting that calling tpm_init() only, doesn't allow a someone
to use the TPM since the startup sequence is mandatory. We always
repeat the pattern of calling
- tpm_init()
- tpm_startup()
- tpm_self_test_full() or tpm_continue_self_test()

The function fdtdec_board_setup() is called early and adds the overlay
from ATF to the u-boot device tree. That is necessary so that u-boot
doesn't use reserved memory.
Linux also needs to know about that reserved memory so the overlay from
ATF needs to be aplied on the linux device tree as well.
This commit makes sure that the ATF overlay is applied to both device trees.

In case RX error occurs, and the RD_RFE bit is set, the descriptor
is never returned back to the queue. Make sh_eth_recv_start return
zero length in this case so that the descriptor can be released
and pushed back to the list. Also return the more appropriate
-EAGAIN instead of -EINVAL if the descriptor is not ready yet.

U-Boot writes to RX packets when constructing replies.
This can cause stale cached data to be written to RX
buffer while we're receiving a packet. This causes RX
packet corruption because we invalidate the cache right
before processing the packet. Invalidate packet buffer
cache when preparing RX descriptor as well. This seems
to fix RX packet drops with high RX traffic.
While at it flush the descriptors right before enabling
RX/TX in sh_eth_tx_desc_init/sh_eth_rx_desc_init callbacks
when they are ready instead of flushing after allocation.

Two sets of FWU updates from Jassi Brar. First:
The patchset reduces ~400 lines of code, while keeping the functionality same and making
meta-data operations much faster (by using cached structures).
Issue:
meta-data copies (primary and secondary) are being handled by the
backend/storage layer instead of the common core in fwu.c (as also noted by
Ilias) that is, gpt_blk.c manages meta-data and similarly raw_mtd.c will have
to do the same when it arrives. The code could by make smaller, cleaner and
optimised.
Basic idea:
Introduce .read_mdata() and .write_mdata() in fwu_mdata_ops that simply
read/write meta-data copy. The core code takes care of integrity and redundancy
of the meta-data, as a result we can get rid of every other callback
.get_mdata() .update_mdata() .get_mdata_part_num() .read_mdata_partition()
.write_mdata_partition() and the corresponding wrapper functions thereby making
the code 100s of LOC smaller.
Get rid of fwu_check_mdata_validity() and fwu_mdata_check() which expected
underlying layer to manage and verify mdata copies.
Implement fwu_get_verified_mdata(struct fwu_mdata *mdata) public function that
reads, verifies and, if needed, fixes the meta-data copies.
Verified copy of meta-data is now cached as 'g_mdata' in fwu.c, which avoids
multiple low-level expensive read and parse calls.
gpt meta-data partition numbers are now cached in gpt_blk.c, so that we don't
have to do expensive part_get_info() and uid ops.
And second:
Introduce support for mtd backed storage for FWU feature and enable it on
Synquacer platform based DeveloperBox.
Just like fwu_plat_get_update_index, provide a default/weak
implementation of fwu_plat_get_bootidx. So that most platforms
wouldn't have to re-implement the likely case.

Any requirement of FWU should not require changes to bindings
of other subsystems. For example, for mtd-backed storage we
can do without requiring 'fixed-partitions' children to also
carry 'uuid', a property which is non-standard and not in the
bindings.
There exists no code yet, so we can change the fwu-mtd bindings
to contain all properties within the fwu-mdata node.
