Overidde the weak function dram_bank_mmu_setup() to set the DDR
(preloc case) or the SYSRAM (in SPL case) executable before to enable
the MMU and configure DACR.
This weak function is called in dcache_enable/mmu_setup.
This patchs avoids a permission access issue when the DDR is marked
executable (by calling mmu_set_region_dcache_behaviour with
DCACHE_DEFAULT_OPTION) after MMU setup and domain access permission
activation with DACR in dcache_enable.

Remove the test on data->dfu_seq, because dfu_seq=0 not only when
the DFU is not started (mask with 0xffff). This flush is mandatory
as the final treatment, common with USB, is done in DFU callback.
This patch avoids issue if the received length is a multiple of
the DFU packet.
For example if size of bootfs partition is egual to 0x4000000,
data->dfu_seq=0 at the end of the partition, the flush it not
requested and the phase is not increased in the callback.
U-Boot continue to request the bootfs in the next GetPhase command.

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 <asm/u-boot.h>
#include <asm/u-boot.h>
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:

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).
