TPM command library implements a subset of TPM commands defined in TCG
Main Specification 1.2 that are useful for implementing secure boot.
More TPM commands could be added out of necessity.
You may exercise these commands through the 'tpm' command. However, the
raw TPM commands are too primitive for writing secure boot in command
interpreter scripts; so the 'tpm' command also provides helper functions
to make scripting easier.
For example, to define a counter in TPM non-volatile storage and
initialize it to zero:
$ tpm init
$ tpm startup TPM_ST_CLEAR
$ tpm nv_define d 0x1001 0x1
$ tpm nv_write d 0x1001 0
And then increment the counter by one:
$ tpm nv_read d 0x1001 i
$ setexpr.l i $i + 1
$ tpm nv_write d 0x1001 $i

UBI is a better place for the environment on NAND devices because it
handles wear-leveling and bad blocks.
Gluebi is needed in Linux to access the env as an MTD partition.
Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
The env in UBI needs to look up the mtd partition as part of relocation,
which happens before relocation. Make the mtdparts code capable of
working on the default env to start with.
The code tries to set values in the env as well, but again, the env
isn't there yet, so add a check to setenv to not allow sets before the
env is relocated.

If watchdog is enabled, the arch/powerpc/lib/ticks.S::wait_ticks() function
calls the function specified by the WATCHDOG_RESET macro.
The wait_ticks function depends on the registers r0, r6 and r7 being
preserved however that is not guaranteed, e.g. if the reset function is a
C function this will probably overwrite r0 and cause an endless loop.
The following patch changes to using r14+r15 instead of r6+r7 (to resemble
what would have been generated by a C compiler) and saves all necessary
registers on the stack.
The patch has been tested on a custom MPC5125 based machine using the 512x
powerpc architecture.

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.
The changes were started by Pantelis and finished by Tom.

Previously we didn't support upload/download larger than available
memory. This is pretty bad when you have to update your root filesystem
for example.
This patch removes that limitation (and the crashes when you transfered
any file larger than 4MB) by making raw image writes be done in chunks
and making file maximum size be configurable.
The sequence number is a 16 bit counter; make sure we handle rollover
correctly. This fixes the wrong transfers for large (> 256MB) images.
Also utilize a variable to handle initialization, so that we don't rely
on just the counter sent by the host.

Often it happens that patches include tags which don't have aliases. It
is annoying that patman fails in this case, and provides no option to
continue other than adding empty tags to the .patman file.
Correct this by adding a '-t' option to ignore tags that don't exist.
Print a warning instead.
Since running the tests is not a common operation, move this to --test
instead, to reserve -t for this new option.

the macro CONFIG_PHYS_64BIT is included in common.h which comes
after div64.h, so in order to get consistent type definition for
phys_addr_t, common.h should be included before div64.h, Or else,
the parameters of phys_addr_t type will be passed wrongly when
