Hello!
Is it possible to store the environment inside a mtd partition when
using a single qspi nand chip as storage?
CONFIG_MTD_SPI_NAND=y
The idea is to separate the NAND into two system A/B.
1.Solution:
mtdparts_nand0=2m(uboot),16m(system)
system will be an ubifs containing env+env_redundant
How can I use TPM in u-boot for secure boot ?
U-Boot has TPM support and it provide some driver support and commands.
I have enabled TPM support in u-boot.
But I don't know how to use it ?
Have anybody used TPM in uboot ?

Add CONFIG_SYS_MONITOR_LEN macro to apollon board config.
CONFIG_SYS_MONITOR_LEN defines the U-Boot image size.
and is used by OneNAND ipl when reading U-Boot image.

Currently OneNAND initial program loader (ipl) reads only block 0 ie 128KB.
However, u-boot image for apollon board is 195KB making the board
unbootable with OneNAND.
Fix ipl to read CONFIG_SYS_MONITOR_LEN.
CONFIG_SYS_MONITOR_LEN macro holds the U-Boot image size.

3. A single device is registered for Flex-OneNAND. This device
has erase regions. Each erase region has different block
size (either SLC or MLC).
4. 4 ECC registers.
5. LSB page recovery feature.

Hi,
The following patches improve partitioning and bad block support
for OneNAND / Flex-OneNAND devices.
The idea is to be able to use U-Boot as a utility to write images
to flash.
Any comments are much appreciated.

At least, I'd like Kyungmin Park's ack for OneNAND stuff.
Basically I acked this patch.
I'll repost after MTD merge.

for storing code and data, such as bootloader, kernel

for storing user data. Users can configure the size of SLC and MLC
regions through 'onenand setboundary' command.
