bd3f60d29c arm: stm32mp: protect DBGMCU_IDC access with BSEC
As debugger must be totally closed on Sec closed chip,
the DBGMCU_IDC register is no more accessible (self
hosted debug is disabled with OTP).

This patch adds a function bsec_dbgswenable() to check
if the DBGMCU registers are available before to access them:
BSEC_DENABLE.DBGSWENABLE = self hosted debug status.

d1a4b09de6 board: st: stpmic1: add function stpmic1_init
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.

164873a0c0 board: stm32mp1: fix handling of DT OP-TEE reserved memory nodes
Fix the sequence in stm32mp1 fdt.c that disables OP-TEE resources
defined in FDT when U-boot detects OP-TEE firmware is not present.

Before this change, helper function stm32_fdt_disable_optee()
set property status to "disabled" for the OP-TEE reserved memory
nodes but this has no impact since Linux kernel does not consider
the status property for reserved-memory subnodes. This change
make U-Boot to attempt to delete the node instead.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward

Drop the typedef and rename the struct to remove the _s suffix which is

dc7e5f190d arm: stm32mp: activate data cache on DDR in SPL
Activate cache on DDR to improve the accesses to DDR used by SPL:
- CONFIG_SPL_BSS_START_ADDR
- CONFIG_SYS_SPL_MALLOC_START

Cache is configured only when DDR is fully initialized,
to avoid speculative access and issue in get_ram_size().
Data cache is deactivated at the end of SPL, to flush the data cache
and the TLB.

7e8471cae5 arm: stm32mp: activate data cache in SPL and before relocation
Activate the data cache in SPL and in U-Boot before relocation.

In arch_cpu_init(), the function early_enable_caches() sets the early
TLB, early_tlb[] located .init section, and set cacheable:
- for SPL, all the SYSRAM
- for U-Boot, all the DDR

After relocation, the function enable_caches() (called by board_r)
reconfigures the MMU with new TLB location (reserved in
board_f.c::reserve_mmu) and re-enable the data cache.

This patch allows to reduce the execution time, particularly
- for the device tree parsing in U-Boot pre-reloc stage
  (dm_extended_scan_fd =>dm_scan_fdt)
- in I2C timing computation in SPL (stm32_i2c_choose_solution())

For example, the result on STM32MP157C-DK2 board is:
   1,6s gain for trusted boot chain with TF-A
   2,2s gain for basic boot chain with SPL

For information, as TLB is added in .data section, the binary size
increased and the SPL load time by ROM code increased (30ms on DK2).

But early malloc can't be used for TLB because arch_cpu_init()
is executed before the early poll initialization done in spl_common_init()
called by spl_early_init() So it too late for this use case.
And if I initialize the MMU and the cache after this function it is
too late, as dm_init_and_scan and fdt parsing is also called in
spl_common_init().

And .BSS can be used in board_init_f(): only stack and global can use
before BSS init done in board_init_r().

So .data is the better solution without hardcoded location but if you
have size issue for SPL you can deactivate cache for SPL only
(with CONFIG_SPL_SYS_DCACHE_OFF).

d0686c69ff stm32mp: stm32prog: support for script
Support an U-Boot script included in uimage instead of flashlayout file
(text file in tsv format).

This feature is used to execute this script directly when U-Boot is
loaded in DDR (for update without STM32CubeProgrammer for example).

A simple example with dfu-util only is:

$> echo "dfu 0" > script.cmd
$> mkimage -C none -A arm -T script -d script.cmd script.uimg
$> mkimage -T stm32image -a 0xC0000000 -e 0xC0000000 -d script.uimg \
  script.stm32

$> dfu-util -d 0483:df11 -a 1 -D tf-a.stm32
$> dfu-util -d 0483:df11 -a 0 -D script.stm32
$> dfu-util -d 0483:df11 -a 0 -D u-boot.stm32
$> dfu-util -d 0483:df11 -a 0 -e

Then you can used dfu-utils to update your device

To increase speed, you can also switch to fastboot protocol with:
  echo "fastboot 0" > script.cmd

954bd1a923 stm32mp: add the command stm32prog
Add a specific command stm32prog for STM32MP soc family
witch allows to program the boot devices with the tool
STM32CubeProgrammer (http://www.st.com/STM32CubeProg).

This command uses the same UART STM32 protocol than MCU
STM32 with or USB with DFU protocol v1.1 (ithe MCU ST
extension are no supported).

The executed actions are based on a tab separated value file
with a stm32 header, the FlashLayout file
(https://wiki.st.com/stm32mpu/wiki/STM32CubeProgrammer_flashlayout).

This file is parsed by the U-Boot command to:
- initialize the devices
- create the partition table on each device
- initialize the DFU backend to access to not volatile memory
  (NOR/NAND/SD/eMMC) or to virtual device (OTP/PMIC)

Up to STM32PROG_MAX_DEV (5) devices can be updated with a FlashLayout.

The communication between U-Boot and STM32CubeProgrammer is done with
the specific alternate configuration (see "AN5275: USB DFU/USART protocols
used in STM32MP1 Series bootloaders" for details).

The command stm32prog is executed when a boot from USB is detected
(selected with bootpins) and we can program the boot devices with
a simple command (on Windows or Linux):

PC $>  STM32_Programmer_CLI -c port=usb1 -w flaslayout.tsv

1/ the ROM code loads TF-A in embedded RAM (DFU or uart)
2/ TF-A loads flashlayout file and U-Boot in DDR (DFU or uart)
3/ U-Boot executes the stm32prog command (DFU or uart)

050fed8a97 stm32mp1: add 800 MHz profile support
The STM32MP1 series is available in 3 different lines which are pin-to-pin
compatible:
- STM32MP157: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz,
              3D GPU, DSI display interface and CAN FD
- STM32MP153: Dual Cortex-A7 cores, Cortex-M4 core @ 209 MHz
              and CAN FD
- STM32MP151: Single Cortex-A7 core, Cortex-M4 core @ 209 MHz

Each line comes with a security option (cryptography & secure boot)
& a Cortex-A frequency option :

- A : Cortex-A7 @ 650 MHz
- C : Secure Boot + HW Crypto + Cortex-A7 @ 650 MHz
- D : Cortex-A7 @ 800 MHz
- F : Secure Boot + HW Crypto + Cortex-A7 @ 800 MHz

This patch adds the support of STM32MP15xD and STM32MP15xF in U-Boot.

7ae22d7278 arm: stm32mp: bsec: add permanent lock support in bsec driver
Add BSEC lock access (read / write) at 0xC0000000 offset of misc driver.
The write access only available for Trusted boot mode, based on new
SMC STM32_SMC_WRLOCK_OTP.

With the fuse command, the permanent lock status is accessed with
0x10000000 offset (0xC0000000 - 0x8000000 for OTP sense/program
divided by u32 size), for example:

Read lock status of fuse 57 (0x39)

  STM32MP> fuse sense 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

Set permanent lock of fuse 57 (0x39)

  STM32MP> fuse prog 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

WARNING: the OTP lock is updated only after reboot

WARING: Programming lock or fuses is an irreversible operation!
        This may brick your system.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.
