STM32F405 has 128K of SRAM and another 64K of CCM (Core-coupled
4
Memory) at a different base address. Correctly describe the memory
5
layout to give existing FW images a chance to run unmodified.

New patch
1
From: Strahinja Jankovic <strahinjapjankovic@gmail.com>
1
2
3
During SPL boot several Clock Controller Module (CCM) registers are
4
read, most important are PLL and Tuning, as well as divisor registers.
5
6
This patch adds these registers and initializes reset values from user's
7
guide.

New patch
1
1
From: Strahinja Jankovic <strahinjapjankovic@gmail.com>
2
3
During SPL boot several DRAM Controller registers are used. Most
4
important registers are those related to DRAM initialization and
5
calibration, where SPL initiates process and waits until certain bit is
6
set/cleared.
7
8
This patch adds these registers, initializes reset values from user's
9
guide and updates state of registers as SPL expects it.

New patch
1
From: Strahinja Jankovic <strahinjapjankovic@gmail.com>
1
2
3
This patch implements Allwinner TWI/I2C controller emulation. Only
4
master-mode functionality is implemented.
5
6
The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is
7
first part enabling the TWI/I2C bus operation.
8
9
Since both Allwinner A10 and H3 use the same module, it is added for
10
both boards.
11
12
Docs are also updated for Cubieboard and Orangepi-PC board to indicate
13
I2C availability.

New patch

From: Strahinja Jankovic <strahinjapjankovic@gmail.com>
1
2
3
This patch adds minimal support for AXP-209 PMU.
4
Most important is chip ID since U-Boot SPL expects version 0x1. Besides
5
the chip ID register, reset values for two more registers used by A10
6
U-Boot SPL are covered.

3
This patch enables copying of SPL from MMC if `-kernel` parameter is not
4
passed when starting QEMU. SPL is copied to SRAM_A.

6
The approach is reused from Allwinner H3 implementation.

Tested with Armbian and custom Yocto image.

48
+ * This function emulates the Boot ROM by copying 32 KiB
49

Since pxa255_init() must map the device in the system memory,

The arm_boot_info struct has a skip_dtb_autoload flag: if this is

code path which is only executed for the case where we load

code path then the flag isn't honoured and the DTB is never

Fix the block comment style in arm_load_kernel() to QEMU's
1
From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
current style preferences. This will allow us to do some
3
refactoring of this function without checkpatch complaining
4
about the code-motion patches.
5
2
3
Since its QOM'ification in commit 368a354f02 ("pflash_cfi0x:
4
QOMified") the pflash_cfi01_register() function does not fail.
5
6
This call was later converted with a script to use &error_fatal,
7
still unable to fail. Remove the unreachable code.

Factor out the "boot via firmware" code path from arm_load_kernel()

From: Philippe Mathieu-Daudé <philmd@linaro.org>

into its own function.

This commit only moves code around; no semantic changes.
3
Following docs/devel/style.rst guidelines, rename omap_gpif_s ->
4
Omap1GpioState. This also remove a use of 'struct' in the
5
DECLARE_INSTANCE_CHECKER() macro call.

ARM trusted firmware, when built with FEAT_HCX support, sets SCR_EL3.HXEn bit
4
to allow EL2 to modify HCRX_EL2 register without trapping it in EL3. Qemu
5
uses a valid mask to clear unsupported SCR_EL3 bits when emulating SCR_EL3
6
write, and that mask doesn't include SCR_EL3.HXEn bit even if FEAT_HCX is
7
enabled and exposed to the guest. As a result EL3 writes of that bit are
8
ignored.
