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

This board is from a u-boot point of view a mixture between kmnusa and
a standard km_kirkwood board. We have our u-boot environment in the spi
NOR flash, but we have a direct connection between the kirkwood and the
piggy. A FPGA is connected via the PCIe interface. So we only have to
select the specific features in the board setup.

The conversion of mx31pdk to SPL NAND fixed the boot issue, but we start seeing
resets in loop, which prevents us from reaching the U-boot prompt.
Until the proper fix can be identified, disable watchdog, so that mx31pdk
can be functional again.

Change CONFIG_SPL_PAD_TO from a link address to an image offset since this is
more handy and closer to the purpose of this config.
Automatically define CONFIG_SPL_PAD_TO to CONFIG_SPL_MAX_SIZE (or 0 without
CONFIG_SPL_MAX_SIZE).
Test that CONFIG_SPL_PAD_TO >= CONFIG_SPL_MAX_SIZE if CONFIG_SPL_PAD_TO is
non-zero.

In the current u-boot, the device pin multiplexing and clock
initialisation needs to be early during the boot process and before
board_init() is called. U-boot is currently crashing on this board
because this is not being done early enough. Therefore, add a s_init()
function for the omap5912-osk board to do this.
Also fix the stack pointer so that it is pointing to the end of the
internal RAM and not the beginning as this was also causing the device
to crash.

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.

The omap5_uevm platform has eMMC, and it makes sense to say that our
default env storage shall reside there. Other platforms may not, so
move this choice to the EVM config. In addition, we should provide some
way to partition the flash for later usage, so take advantage of the GPT
partition table support code and allow that to be setup with some
reasonable defaults.

For production systems it is better to use script images since
they are protected by checksums and carry valuable information
like name and timestamp. Also, you can't validate the content
passed to env import.
But for development, it is easier to use the env import command and
plain text files instead of script-images.
Since both OMAP5evm/uevm boards are used primarily for development,
we allow U-Boot to load env var from a text file in case that an
boot.scr script-image is not present.
The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

Enable device-tree support for the omap2420-h4 board.
Signed-off-by: Jon Hunter <[email protected]>
|
|
The omap2420-h4 board is using a RAM based address as the linker
location for code. This is causing several problems when attempting
to run the latest u-boot code base on this board from flash. Update
the default linker location for code to be in NOR flash. Please note
that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.
Also remove legacy code that attempts to calculate where in flash the
sdata structure, that holds the memory interface configuration data,
is located. By changing the default linker location for code to flash
this is no longer necessary.
