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 ?

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.

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.

okay. but why not use a variable instead.

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.
