87d43329ef binman: Move GetEntryModules() to control
When binman is installed its main program is in a different directory
to its modules. This means that __file__ is different and we cannot use
it to obtain the path to etype/ from main.py

To fix this, move the function to the 'control' module, since it is
installed with all the other modules, including the etype/ directory.

702e57e113 treewide: convert devfdt_get_addr_ptr() to dev_read_addr_ptr()
When you enable CONFIG_OF_LIVE, you will end up with a lot of
conversions.

To help this tedious work, this commit converts devfdt_get_addr_ptr()
to dev_read_addr_ptr() by coccinelle. I also removed redundant casts
because dev_read_addr_ptr() returns an opaque pointer.

To generate this commit, I ran the following semantic patch
excluding include/dm/.

  <smpl>

1450bff3e4 ata: mvebu: use dev_read_addr() to get base address
It is strange to use devfdt_get_addr_ptr(), then cast the pointer
back to ulong because you could use devfdt_get_addr() without casting.

Convert it to dev_read_addr(), which is capable to CONFIG_OF_LIVE.

3fe69d3764 dm: core: Fix devfdt_get_addr_ptr return value
According to the description of devfdt_get_addr_ptr, this function should
return NULL on failure, but currently it returns (void *)FDT_ADDR_T_NONE.

Fix this by making devfdt_get_addr_ptr return NULL on failure, as
described in the function comments. Also, update the drivers currently
checking (void *)FDT_ADDR_T_NONE to check for NULL.

e37d4c4fd2 test/py: Update test_bind
As bind-test is now binded at sandbox startup and no more by
test_bind.py, bind-test nodes are not located at the end of
"dm tree" output, but can be located everywhere in the tree, so
bind-test output could either be:

 simple_bus    0  [   ]   generic_simple_bus    |-- bind-test
 phy           0  [   ]   phy_sandbox           |   |-- bind-test-child1
 simple_bus    1  [   ]   generic_simple_bus    |   `-- bind-test-child2

or:

 simple_bus    5  [   ]   generic_simple_bus    `-- bind-test
 phy           2  [   ]   phy_sandbox               |-- bind-test-child1
 simple_bus    6  [   ]   generic_simple_bus        `-- bind-test-child2

in_tree() function need to be updated to take care of that change.

1f0d5885db sandbox: dts: Add compatible string for bind-test node
Usage of lists_bind_fdt() in bind command imposes to add
a compatible string for bind-test node.

Others impacts are:
  - bind-test node is binded at sandbox start, so no need to bind it
    in test_bind_unbind_with_node() test.
  - As explained just above, after sandbox start, now a phy exist.
    In test/dm/phy.c, it was verified that a third phy didn't exist,
    now we must verified that a fourth phy doesn't exist.

84f8e36f03 cmd: bind: allow to bind driver with driver data
Initial implementation invokes device_bind_with_driver_data()
with driver_data parameter equal to 0.
For driver with driver data, the bind command can't bind
correctly this driver or even worse causes data abort as shown below:

As example, for debug purpose on STM32MP1 platform, ethernet
(dwc_eth_qos.c) driver needed to be unbinded/binded.
This driver is using driver data:

static const struct udevice_id eqos_ids[] = {
    {
        .compatible = "nvidia,tegra186-eqos",
        .data = (ulong)&eqos_tegra186_config
    },
    {
        .compatible = "snps,dwmac-4.20a",
        .data = (ulong)&eqos_stm32_config
    },

    { }
};

After unbinding/binding this driver and probing it (with the dhcp command),
we got a prefetch abort as below:

STM32MP> unbind eth ethernet@5800a000
STM32MP> bind /soc/ethernet@5800a000 eth_eqos

ae6b33dcc3 dm: fix ofnode_read_addr/size_cells()
In the case of the live tree ofnode_read_addr_cells() and
ofnode_read_size_cells() return the #address-cells and #size-cells defined
in the parent node. With the patch the same is done for a non-live tree.

The only consumer of these functions is currently the CFI flash driver.

This patch fixes the incorrect parsing of the device tree leading to
'saveenv' failing on qemu_arm64_defconfig.

For testing qemu-system-aarch64 has to be called with

    -drive if=pflash,format=raw,index=1,file=envstore.img

to provide the flash memory. envstore.img must be 64 MiB large.

fdtdec_setup_mem_size_base() is not enough because this memory can be above
actual U-Boot VA mapping. Currently only mapping till 39bit is supported
(Full 44bit mapping was removed by commit 7985cdf74b ("arm64: Remove
non-full-va map code")).
If DT starts with the first memory node above 39bit address then system can
be unpredictable.

The function is available only when multiple memory bank support is
enabled.

Calling fdtdec_setup_memory_banksize() from dram_init() is not possible
because fdtdec_setup_memory_banksize() is saving dram information to bd
structure which is placed on stack but not initialized at this time. Also
stack is placed at location setup in dram_init().

11b1dcec09 versal: fix versal PM ret payload size
The PM return payload size is defined as 4 bytes for Versal arquitecture
while the PM calls implemented both in the Versal clock driver and
ZynqMP firmware driver expects 5 bytes length.

1b208d59ba arm64: zynqmp: Fix set_fdtfile() not to break u-boots DTB
Origin function was calling strsep which replaced delimiter ',' by a null
byte ('\0'). Operation was done directly on FDT which ends up with the
following behavior:

ZynqMP>  printenv fdtfile
fdtfile=xilinx/zynqmp.dtb
ZynqMP> fdt addr $fdtcontroladdr
ZynqMP> fdt print / compatible
compatible = "xlnx", "zynqmp"

As is visible fdtfile was correctly composed but a null byte caused that
xlnx was separated from zynqmp.
This hasn't been spotted because in all Xilinx DTs there are at least 3
compatible string and only the first one was affected by this issue.
But for systems which only had one compatible string "xlnx,zynqmp" it was
causing an issue when U-Boot's DT was used by Linux kernel.

The patch removes strsep calling and strchr is called instead which just
locate the first char after deliminator ',' (variable called "name").
And using this pointer in fdtfile composing.

Fixes: 91d7e0c47f ("arm64: zynqmp: Create fdtfile from compatible string")

c8da6513c0 xilinx: Setup bootm variables
On system with PL DDR which is placed before PS DDR in DT
env_get_bootm_size() and env_get_bootm_low() without specifying bootm_low
and bootm_size variables are taking by default gd->bd->bi_dram[0].start and
gd->bd->bi_dram[0].size. As you see 0 means bank 0 which doesn't need to be
PS ddr and even can be memory above 39bit VA which is what U-Boot supports
now.
That's why setup bootm variables based on ram_base/ram_size setting to make
sure that boot images are placed to the same location as U-Boot is placed.
This location should be by default location where OS can boot from.
