4364071362 pci: pci_mvebu: Add support for Kirkwood PCIe controllers
Kirkwood uses macros KW_DEFADR_PCI_MEM and KW_DEFADR_PCI_IO for base
address of PCIe mappings. Size of PCIe windows is not defined in any macro
yet, so export them in new KW_DEFADR_PCI_MEM_SIZE and KW_DEFADR_PCI_IO_SIZE
macros.

Kirkwood arch code already maps mbus windows for io and mem, so avoid
calling mvebu_mbus_add_window_by_id() function which would try to do
duplicate window mapping.

Kirkwood PCIe controllers already use "marvell,kirkwood-pcie" DT compatible
string, so mark pci_mvebu.c driver as compatible for it.

According to the PE-COFF specification [1] the minimum value for
FileAlignment is 512. If the value of SectionAlignment is
less then the page size, it must equal FileAlignment.

Let's set both values to 512 for the ARM and RISC-V architectures.

BootROM has its output on UART disabled by default.

To enable BootROM output on A38x SoC, it is required to set DEBUG flag

images this DEBUG flag is ignored by BootROM.

Enable kwbimage DEBUG flag for all A38x boards.

a2b1db41cf arm: mvebu: Correctly set LOAD_ADDRESS for U-Boot SPL binary in kwbimage
U-Boot SPL for mvebu platform is not compiled as position independent.
Therefore it is required to instruct BootROM to load U-Boot SPL at the
correct address. Loading of kwbimage binary code at specific address can be
now achieved by the new LOAD_ADDRESS token as part of BINARY command in
kwbimage config file.

Update mvebu Makefile to put value of $(CONFIG_SPL_TEXT_BASE) into
LOAD_ADDRESS token when generating kwbimage.cfg from kwbimage.cfg.in.

It is required to update regex for sed to find replacement tokens at any
position on a line in kwbimage config file and not only at the beginning of
the line. This is because LOAD_ADDRESS is specified at the end of line
containing the BINARY command.

It looks like all Armada boards set CONFIG_SPL_TEXT_BASE to value
0x40004030 or 0x40000030. Why this value? It is because main kwbimage
header is at address 0x40004030 or 0x40000000 and it is 32 bytes long.
After the main header there is the binary header, which consist of 1 byte
for type, 3 bytes for size, 1 byte for number of arguments, 3 reserved
bytes and then 4 bytes for each argument. After these arguments comes the
executable code.

So arguments start at address 0x40004028 or 0x40000028. Before commit
e6571f38c9 ("arm: mvebu: Remove dummy BIN header arguments for SPL
binary") there were two (dummy) arguments, which resulted in load address
of 0x40004030 or 0x40000030, always. After that commit (which removed dummy
arguments), load address stayed same due to the 128-bit alignment done by
mkimage.

This patch now reflects the dependency between $(CONFIG_SPL_TEXT_BASE),
load address and dummy kwbimage arguments, and allows the user to adjust
$(CONFIG_SPL_TEXT_BASE) config option to some other value.

For unsupported values, when mkimage/kwbimage cannot set chosen load address
as specified by $(CONFIG_SPL_TEXT_BASE), the build process now fails,
instead of silently generating non-working kwbimage.

Removal of this alignment between $(CONFIG_SPL_TEXT_BASE) and LOAD_ADDRESS
can only be done by compiling U-Boot SPL as position independent. But this
currently is not possible for 32-bit ARM version of U-Boot SPL.

Usage of $(call cmd,...) is standard way to call other commands which
generate things.

It also has the advantage of printing build information in the form
  KWBCFG  arch/arm/mach-mvebu/kwbimage.cfg
if verbosity is disabled, and printing the build command otherwise.

Note that the '#' character needs to be escaped in Makefile when used as
value for make variable assignment.

c03f4da187 mtd: nand: pxa3xx: use marvell, prefix for custom DT properties
The DT properties for the "enable-arbiter" and "keep-config" config
knobs were previously named inconsistently:

- The u-boot driver used "nand-enable-arbiter" and "nand-keep-config"
  names, without Marvell prefixes.

- The Linux driver uses "marvell,nand-keep-config" ("enable-arbiter"
  does not exist anymore in recent kernels, but it also used to be
  "marvell,nand-enable-arbiter").

- The device trees almost all use "marvell," prefixed names, except for
  one single instance of "nand-enable-arbiter" without vendor prefix.

This commit standardizes on the vendor prefixed version, making the
u-boot driver read from DT props "marvell,nand-enable-arbiter" and
"marvell,nand-keep-config". The one device tree using the unprefixed
version is also changed to use the new naming.

This has the side effect of making the previously no-op "marvell,"
config knobs already present in some DTs actually do something. This was
likely the original intention of the DT authors, but note that this
commit was not tested on every single impacted board.

94c30f9c8f arm: mvebu: a38x: serdes: Move non-serdes PCIe code to pci_mvebu.c
As explained in commit 3bedbcc3aa ("arm: mvebu: a38x: serdes: Don't
overwrite read-only SAR PCIe registers") it is required to set Maximum Link
Width bits of PCIe Root Port Link Capabilities Register depending of number
of used serdes lanes. As this register is part of PCIe address space and
not serdes address space, move it into pci_mvebu.c driver.

Read number of PCIe lanes from DT property "num-lanes" which is used also
by other PCIe controller drivers in Linux kernel. If this property is
absent then it defaults to 1. This property needs to be set to 4 for every
mvebu board which use PEX_ROOT_COMPLEX_X4 or PEX_BUS_MODE_X4.

Enabling of PCIe port needs to be done afer all registers in PCIe address
space are properly configure. For this purpose use new mvebu-reset driver
(part of system-controller) and remove this code from serdes code.

Because some PCIe ports cannot be enabled individually, it is required to
first setup all PCIe ports and then enable them.

This change contains also all required "num-lanes" and "resets" DTS
properties, to make pci_mvebu.c driver work correctly.

35e29e89a3 arm: mvebu: Implement simple mvebu-reset driver for enabling/disabling PCIe ports
Enabling and disabling PCIe ports is done via address space of system
controller. All 32-bit Armada SoCs use low 4 bits in SoC Control 1 Register
for enabling and disabling some or more PCIe ports. Correct mapping needs
to be set in particular DTS files.

DT API for mvebu-reset is prepared for implementing resets also for other
HW blocks, but currently only PCIe is implemented via index 0.

Currently this driver is not used as PCIe ports are automatically enabled
by SerDes code executed by U-Boot SPL. But this will change in followup
patches.

537b0142b0 pci: pci_mvebu: Fix PCIe MEM and IO resources assignment and mbus mapping
Do not call pci_set_region() for resources which were not properly mapped.
This prevents U-Boot to access unmapped memory space.

Update MBUS_PCI_MEM_SIZE and MBUS_PCI_IO_SIZE macros to cover all PCIe MEM
and IO ranges. Previously these macros covered only address ranges for the
first PCIe port. Between MBUS_PCI_IO_BASE and MBUS_PCI_MEM_BASE there is
space for six 128 MB long address ranges. So set MBUS_PCI_MEM_SIZE to value
of 6*128 MB. Similarly set MBUS_PCI_IO_SIZE to 6*64 KB.

Function resource_size() returns zero when start address is 0 and end
address is -1. So set invalid resources to these values to indicate that
resource has no mapping.

Split global PCIe MEM and IO resources (defined by MBUS_PCI_*_* macros)
into PCIe ports in mvebu_pcie_bind() function which allocates per-port
based struct mvebu_pcie, instead of using global state variables
mvebu_pcie_membase and mvebu_pcie_iobase. This makes pci_mvebu.c driver
independent of global static variables (which store the state of
allocation) and allows to bind and unbind the driver more times.

8f9e0f4d20 arm: mvebu: Convert board_pex_config() to CONFIG_SPL_BOARD_INIT
The only user of board_pex_config() weak function is A385 controlcenterdc
board. It looks like that code in its board_pex_config() function needs to
be executed after PCIe link is up. Therefore put this code into
spl_board_init() function which is called after a38x serdes initialization,
and therefore it is after the serdes hws_pex_config() function finishes
(which is the state before this change).

With this change completely remove board_pex_config() function as it is not
used anymore.
