stm32mp1: add support for stm32mp157c-ev1 board
Add support of stm32mp157c-ev1, the evaluation board with pmic stpmu1
(ev1 = mother board + daughter ed1) with device tree.
EV1 is the selected board by default in basic defconfig.
PS: CONFIG_PINCTRL_FULL activation avoid to increase

9. MAC Address
|
||||
==============
|
||||
|
||||
Please read doc/README.enetaddr for the implementation guidelines for mac id
|
||||
usage. Basically, environment has precedence over board specific storage.
|
||||
|
||||
Mac id storage and retrieval in stm32mp otp :
|
||||
- OTP_57[31:0] = MAC_ADDR[31:0]
|
||||
- OTP_58[15:0] = MAC_ADDR[47:32]
|
||||
|
||||
To program a MAC address on virgin OTP words above, you can use the fuse command
|
||||
on bank 0 to access to internal OTP:
|
||||
|
||||
example to set mac address "12:34:56:78:9a:bc"
|
||||
|
||||
1- Write OTP
|
||||
STM32MP> fuse prog -y 0 57 0x78563412 0x0000bc9a
|
||||
|
||||
2- Read OTP
|
||||
STM32MP> fuse sense 0 57 2
|
||||
Sensing bank 0:
|
||||
Word 0x00000039: 78563412 0000bc9a
|
||||
|
||||
3- next REBOOT :
|
||||
### Setting environment from OTP MAC address = "12:34:56:78:9a:bc"
