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.

The SPL boot for Cubieboard expects AXP209 PMIC on TWI0/I2C0 bus, so this is
7
first part enabling the TWI/I2C bus operation.

Since both Allwinner A10 and H3 use the same module, it is added for
10
both boards.

Docs are also updated for Cubieboard and Orangepi-PC board to indicate

I2C availability.

New patch
1
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.
5
6
The approach is reused from Allwinner H3 implementation.

Tested with Armbian and custom Yocto image.

Upon introduction in commit b8433303fb ("Set proper device-width

5
qdev_init_nofail() which can not fail. This call was later

converted with a script to use &error_fatal, still unable to
7
fail. Remove the unreachable code.

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.

In 60592cfed2 ("hw/arm/virt: dt: add kaslr-seed property"), the
3
Following docs/devel/style.rst guidelines, rename omap2_gpif_s ->
4
kaslr-seed property was added, but the equally as important rng-seed
4
Omap2GpioState. This also remove a use of 'struct' in the
5
property was forgotten about, which has identical semantics for a
5
DECLARE_INSTANCE_CHECKER() macro call.
6
similar purpose. This commit implements it in exactly the same way as
7
kaslr-seed. It then changes the name of the disabling option to reflect
8
that this has more to do with randomness vs determinism, rather than
9
something particular about kaslr.

The target/arm/helper.c file is very long and is a grabbag of all
1
From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
kinds of functionality. We have already a debug_helper.c which has
3
code for implementing architectural debug. Move the code which
4
defines the debug-related system registers out to this file also.
5
This affects the define_debug_regs() function and the various
6
functions and arrays which are used only by it.

8
The functions raw_write() and arm_mdcr_el2_eff() and
3
Following docs/devel/style.rst guidelines, rename
9
define_debug_regs() now need to be global rather than local to
4
stellaris_adc_state -> StellarisADCState. This also remove a
10
helper.c; everything else is pure code movement.

use of 'struct' in the DECLARE_INSTANCE_CHECKER() macro call.

In commit 39a1fd25287f5d we fixed a bug in the handling of LPAE block
1
From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
descriptors where we weren't correctly zeroing out some RES0 bits.
3
However this fix has a bug because the calculation of the mask is
4
done at the wrong width: in
5
descaddr &= ~(page_size - 1);
6
page_size is a target_ulong, so in the 'qemu-system-arm' binary it is
7
only 32 bits, and the effect is that we always zero out the top 32
8
bits of the calculated address. Fix the calculation by forcing the
9
mask to be calculated with the same type as descaddr.
10
2
11
This only affects 32-bit CPUs which support LPAE (e.g. cortex-a15)
3
This model was merged few days before the QOM cleanup from
12
when used on board models which put RAM or devices above the 4GB
4
commit 8063396bf3 ("Use OBJECT_DECLARE_SIMPLE_TYPE when possible")
13
mark and when the 'qemu-system-arm' executable is being used.
5
was pulled and merged. Manually adapt.
14
It was also masked in 7.0 by the main bug reported in
15
https://gitlab.com/qemu-project/qemu/-/issues/1078 where the
16
virt board incorrectly does not enable 'highmem' for 32-bit CPUs.
17

The workaround is to use 'qemu-system-aarch64' with the same

The "OS Lock" in the Arm debug architecture is a way for software
1
From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
to suppress debug exceptions while it is trying to power down
3
a CPU and save the state of the breakpoint and watchpoint
4
registers. In QEMU we implemented the support for writing
5
the OS Lock bit via OSLAR_EL1 and reading it via OSLSR_EL1,
6
but didn't implement the actual behaviour.
7
2
8
The required behaviour with the OS Lock set is:
3
This remove a use of 'struct' in the DECLARE_INSTANCE_CHECKER()
9
* debug exceptions (apart from BKPT insns) are suppressed
4
macro call, to avoid after a QOM refactor:
10
* some MDSCR_EL1 bits allow write access to the corresponding
11
EDSCR external debug status register that they shadow
12
(we can ignore this because we don't implement external debug)
13
* similarly with the OSECCR_EL1 which shadows the EDECCR
14
(but we don't implement OSECCR_EL1 anyway)
15
5
16
Implement the missing behaviour of suppressing debug
6
hw/timer/xilinx_timer.c:65:1: error: declaration of anonymous struct must be a definition
17
exceptions.

Fixes a bug in that we were not honoring MTE from user-only
3
ARM trusted firmware, when built with FEAT_HCX support, sets SCR_EL3.HXEn bit
4
SVE. Copy the user-only MTE logic from allocation_tag_mem
4
to allow EL2 to modify HCRX_EL2 register without trapping it in EL3. Qemu
5
into sve_probe_page.
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.
