ARM: dts: stm32: Update eth1addr from EEPROM if eth1 present

2020-08-13T07:56:44+00:00

The STM32MP1 DHCOM has two ethernet interfaces, the on-SoM DWMAC and KS8851.
Set eth1addr for the KS8851 to a MAC address of the DWMAC incremented by 1.
The MAC of the DWMAC is set from on-SoM EEPROM already, but the MAC address
of KS8851 was left uninitialized, so fix this.

ARM: stm32: Add fitImage its entry for 587-200 DHCOR SoM

2020-08-13T07:56:01+00:00

The new 587-200 DHCOR SoM is compatible with the 587-100 prototype,
hence just replicate the entries, as there is no pattern matching.

ARM: stm32: Add both PDK2 and DRC02 DT into DHCOM fitImage its

2020-08-13T07:55:58+00:00

Include both PDK2 and DRC02 DTs in the DHCOM fitImage .its and implement
support in SPL to select the correct configuration entry for U-Boot by
using the machine compatible string from SPL DT.

board: dh_stm32mp1: remove env location override

2020-07-28T15:36:27+00:00

Overriding the environment location is not necessary as the defconfig
for the relevant boards only enable SPI flash and nowhere sources which
are in the same order per default but having this explicit override
prevents using eMMC or SD card (or EXT4) as environment source.

treewide: convert bd_t to struct bd_info by coccinelle

2020-07-17T13:30:13+00:00

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include 

  #include 
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info

board: stm32mp1: update vddcore in SPL

2020-07-07T14:01:23+00:00

For board using STPMIC1, the vddcore is provided by BUCK1 of STPMIC1
and need to be updated for 800MHz support and only after the clock
tree initialization.

The VDDCORE voltage value is provided by clock driver, saved in global
variable opp_voltage_mv and udpated in SPL board_early_init_f(),
just after clock tree initialization.

board: st: stpmic1: add function stpmic1_init

2020-07-07T14:01:23+00:00

Add a function stmpic_init to early initialize the PMIC STPMIC1
- keep vdd on during the reset cycle (to avoid issue when backup battery
  is absent)
- Check if debug is enabled to program PMIC according to the bit

This patch allows to remove the compilation of spl.c file from stm32mp1
board in dh_stm32mp1.

CONFIG_SPL_BOARD_INIT is removed as the new function is called earlier
in SPL, in the function board_early_init_f.

This is needed to obtain the MAC from EEPROM/OTP only after the final
env is populated, otherwise the ethaddr might be overriden.
