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.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.Signed-off-by: Tom Rini

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.Signed-off-by: Tom Rini

This allows to controls the memory internal mapping at
address 0x0000 0000.
We can either map at 0x0000 0000 :
_ main flash memory
_ system flash memory
_ FMC bank1 (NOR/PSRAM 1 and 2)
_ embedded SRAM
_ FMC/SDRAM bank1This is needed for future STM32F469-disco board

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
//
@@@@
-error
+pr_err
(...)

STM32F7 and H7 shared the same SDRAM control block.
On STM32H7 few control bits has been added.
The current driver need some minor adaptation as FMC block

FMC is able to manage 2 SDRAM banks, but the current driver
implementation is only able to manage the first SDRAM bank.Even if only bank2 is used, some bank1 registers must be

Retrieve RAM base address from DT instead of using STM32_SDRAM_FMC
For STM32F7, FMC block base address is 0xA0000000, but SDRAM
registers are located at offset 0x140 inside FMC block.
Update the stm32_fmc_regs fields with all FMC registers
to map SDRAM registers at the right address.These additionals registers will be used later.

Migrate all FMC defines from arch/arm/include/asm/arch-stm32f7/fmc.h

Actually the sdram memory on stm32f746 discovery board is micron part
MT48LC_4M32_B2B5_6A. This patch does the modification required in the
device tree node & driver for the same.Also we are passing here all the timing parameters in terms of clock
cycles, so no need to convert time(ns or ms) to cycles.Signed-off-by: Vikas Manocha
