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.

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

The approach is reused from Allwinner H3 implementation.

3
Upon introduction in commit b8433303fb ("Set proper device-width

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

This is simple apart from the awkward case of Thumb1, where the

then moves from disas_thumb2_insn() to disas_thumb_insn().

The common situation of the SG instruction is that it is
1
From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
executed from S&NSC memory by a CPU in NS state. That case
3
is handled by v7m_handle_execute_nsc(). However the instruction
4
also has defined behaviour in a couple of other cases:
5
* SG instruction in NS memory (behaves as a NOP)
6
* SG in S memory but CPU already secure (clears IT bits and
7
does nothing else)
8
* SG instruction in v8M without Security Extension (NOP)

These can be implemented in translate.c.

Recent changes have left insn_crosses_page() more complicated

From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
than it needed to be:
3
* it's only called from thumb_tr_translate_insn() so we know
4
for certain that we're looking at a Thumb insn
5
* the caller's check for dc->pc >= dc->next_page_start - 3
6
means that dc->pc can't possibly be 4 aligned, so there's
7
no need to check that (the check was partly there to ensure
8
that we didn't treat an ARM insn as Thumb, I think)
9
* we now have thumb_insn_is_16bit() which lets us do a precise
10
check of the length of the next insn, rather than opencoding
11
an inaccurate check
12
2
13
Simplify it down to just loading the first half of the insn
3
The structure is named SECUREECState. Rename the type accordingly.
14
and calling thumb_insn_is_16bit() on it.

The code which implements the Thumb1 split BL/BLX instructions
1
From: Philippe Mathieu-Daudé <philmd@linaro.org>
2
is guarded by a check on "not M or THUMB2". All we really need
3
to check here is "not THUMB2" (and we assume that elsewhere too,
4
eg in the ARCH(6T2) test that UNDEFs the Thumb2 insns).
5
2
6
This doesn't change behaviour because all M profile cores
3
This model was merged few days before the QOM cleanup from
7
have Thumb2 and so ARM_FEATURE_M implies ARM_FEATURE_THUMB2.
4
commit 8063396bf3 ("Use OBJECT_DECLARE_SIMPLE_TYPE when possible")
8
(v6M implements a very restricted subset of Thumb2, but we
5
was pulled and merged. Manually adapt.
9
can cross that bridge when we get to it with appropriate
10
feature bits.)

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.
