For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.
Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.
Given below is the placement of various data sections in SRAM

U-Boot either supports USB host or device mode for a node at a time in the
device tree nodes. To support both host and dfu bootmodes, dr_mode is set
to "peripheral" by default and then fixed based on the mode selected by
the boot mode config dip switches on the board.
This needs to happen before the cdns3 generic layer binds the usb device
to a host or a device driver. Therefore, use fdtdec_setup_board()
implementation to fixup the device tree property.

To quote Simon, first for the display changes:
At present we have two ways of showing a hex dump. Once has been in
U-Boot since the dawn of time and the other was recently added from
Linux.
They both have their own unique features.
This series makes a few changes to bring them closer together. It also
adds support for logging a buffer, which is useful since it can put it
through the same log drivers as other logging output.
Also it adds tests, so we can check the behaviour.
And then the logging changes:
At present when logging is not enabled, all log() calls become nops.
This does not seem right, since if the log level is high enough then
there should be some sort of message. So in that case, this series
updates it to print the message if the log level is above LOGL_INFO.
This mimics the behaviour for the log_...() macros like log_debug() and
log_info(), so we can drop the special case for these.
Also the current implementation does not support multiple log calls on
the same line nicely. The tags are repeated so the line is very hard to
read. This series adds that as a new feature.
At present if logging not enabled, log_info() becomes a nop. But we want
log output at the 'info' level to be akin to printf(). Update the macro to
pass the output straight to printf() in this case.
This mimics the behaviour for the log_...() macros like log_debug() and
log_info(), so we can drop the special case for these.
Add new tests to cover this case.

At present print_buffer() outputs a hex dump but it is not possible to

At present print_hex_dump() only supports either 16- or 32-byte lines.

print_buffer().

The current implementation outputs an address as a pointer. Update the

Add some initial tests copied from print_test_display_buffer(), just the

Note that for this case print_hex_dump() and print_bufffer() produce the

To quote the series author, Patrick Delaunay:
On STM32MP15x platform we can use OP-TEE, loaded in DDR in a region
protected by a firewall. This region is reserved in the device with
the "no-map" property as defined in the binding file
doc/device-tree-bindings/reserved-memory/reserved-memory.txt.
Sometime the platform boot failed in U-Boot on a Cortex A7 access to
this region (depending of the binary and the issue can change with compiler
version or with code alignment), then the firewall raise an error,
for example:
E/TC:0 tzc_it_handler:19 TZC permission failure
E/TC:0 dump_fail_filter:420 Permission violation on filter 0
E/TC:0 dump_fail_filter:425 Violation @0xde5c6bf0, non-secure privileged read,
AXI ID 5c0
E/TC:0 Panic
After investigation, the forbidden access is a speculative request performed
by the Cortex A7 because all the DDR is mapped as MEMORY with CACHEABLE
property.
The issue is solved only when the region reserved by OP-TEE is no more
mapped in U-Boot as it is already done in Linux kernel.
Tested on DK2 board with OP-TEE 3.12 / TF-A 2.4:
With hard-coded address for OP-TEE reserved memory,
the error doesn't occur.
void dram_bank_mmu_setup(int bank)
{
....
for (i = start >> MMU_SECTION_SHIFT;
i < (start >> MMU_SECTION_SHIFT) + (size >> MMU_SECTION_SHIFT);
i++) {
option = DCACHE_DEFAULT_OPTION;
if (i >= 0xde0)
option = INVALID_ENTRY;
set_section_dcache(i, option);
}
}
Just by modifying the test on 0xde0 to 0xdf0, the OP-TEE memory protected
by firewall is mapped cacheable and the error occurs.
I think that it can be a general issue for ARM architecture: the "no-map" tag
of reserved memory in device should be respected by U-Boot if firewall
is configured before U-Boot execution.
But I don't propose a generic solution in
arm/lib/cache-cp15.c:dram_bank_mmu_setup()
because the device tree parsing done in lmb_init_and_reserve() takes a
long time when it is executed without data cache.
No more map the reserved region with "no-map" property by marking
the corresponding TLB entries with invalid entry (=0) to avoid
speculative access.
The device tree parsing done in lmb_init_and_reserve() takes a
long time when it is executed without data cache, so it is called in
enable_caches() before to disable it.
This patch fixes an issue where predictive read access on secure DDR
OP-TEE reserved area are caught by firewall.

While this is an error for 'ranges', this is fine because DMA capable
devices always have a translatable DMA address. Also, with no
'dma-ranges' at all, the assumption is that DMA addresses are 1:1 with
