c519b82e7c imx8mq_phanbell: Remove custom CONFIG_SYS_MALLOC_F_LEN
Currently, the imx8mq_phanbell board fails to boot.

Remove the custom CONFIG_SYS_MALLOC_F_LEN setting in favor of the
generic one done via the main Kconfig.

Since commit b598957206 ("Kconfig: Fix SYS_MALLOC_F_LEN for i.MX8MQ")
the default SYS_MALLOC_F_LEN value for i.MX8MQ is 0x2000.

With such default value, the board boots again.

5004901efb board_init: Do not reserve MALLOC_F area on stack if non-zero MALLOC_F_ADDR
In case the MALLOC_F_ADDR is set to non-zero value, the early malloc area is
not going to be placed just below stack top, but elsewhere. Do not reserve
MALLOC_F bytes in this case, as that wastes stack space and may even cause
insufficient stack space in SPL.

This functionality is particularly useful on i.MX8M, where the insufficient
stack space can be triggered.

5e998b4de3 serial: ns16550: Wait in debug_uart_init until tx buffer is empty
Commit d293759d55 ("serial: ns16550: Add support for
SPL_DEBUG_UART_BASE") fixed support for setting correct early debug UART
base address in SPL.

But after this commit, output from Marvell A385 BootROM is truncated or
lost and not fully present on serial console.

Debugging this issue showed that BootROM just put bytes into UART HW output
buffer and does not wait until UART HW transmit all characters. U-Boot
ns16550 early debug is initialized very early and during its initialization
is resetting UART HW and flushing remaining transmit buffer (which still
contains BootROM output).

Fix this issue by waiting in init function prior resetting UART HW until
TxEmpty bit in UART Line Status Register is set. TxEmpty is set when all
remaining bytes from HW buffer are transmitted.

7886c45d42 mtd: rawnand: Add support to dedicated function to set timings
With the current code if the board has an ONFI compliant NAND without
support to the get and set features, U-boot returns an ENOTSUP error when
trying to tune the timings which prevents the probe of the device.
Indeed onfi_set_features() return ENOTSUP error if set/get features is not
supported. In the case of timings we should not return ENOTSUP because we
can use the default timings. The NAND is already capable of listening at
its highest supported rate, so we assume in this case that it is fine to
skip the operation.

Fix it by adding an intermediate nand_onfi_set_timings() function which
does not error out if set/get feature is not supported.

8142c4554f fw_env: add fallback to Linux's NVMEM based access
A new DT binding for describing environment data block has been added in
Linux's commit 5db1c2dbc04c ("dt-bindings: nvmem: add U-Boot environment
variables binding"). Once we get a proper Linux NVMEM driver it'll be
possible to use Linux's binary interface for user-space as documented
in the:
https://www.kernel.org/doc/html/latest/driver-api/nvmem.html

This commits makes fw_env fallback to looking for a compatible NVMEM
device in case config file isn't present. In a long term this may make
config files redundant and avoid code (info) duplication.

e6ca148104 distroboot: Fix ubifs
Fix multiple issues in ubifs distroboot code:

U-Boot supports attaching only one MTD device as UBI at the time. So
always call 'ubifsmount ubi0:${bootubivol}' for mounting UBI volume
${bootubivol}. Usage of 'ubi${devnum}' is incorrect as 'ubi part'
command attach MTD device always as UBI device ubi0.

Set distroboot ${bootfstype} variable to ubifs in ubifs_boot command.
Distroboot scripts require ${bootfstype} variable to be properly set and it
is already set for all other boot types.

Set distroboot ${distro_bootpart} variable to ${bootubivol} value. UBI
device does not have partitions, but has volumes. Distroboot scripts
require something to be set in ${distro_bootpart} variable, so set it to
the UBI volume which is currently mounted by ubifs.

Set distroboot ${devnum} variable to fixed string "ubi0". ubifs code
differs from the other partition code that it requires "ubi" prefix before
number.

Explicitly unmount ubifs volume after loading all data from it. This allows
to detach UBI device from MTD device.

Move definition of MTD device with UBI and UBI volume with ubifs filesystem
from global env variables ${bootubipart} and ${bootubivol} into the
distroboot "func" macro, defined in board include config files. UBIFS
distroboot macros then set ${bootubipart} and ${bootubivol} local variables
for compatibility with existing distroboot scripts.

This last change allows to define more UBIFS target devices and make it
clear what is boot MTD/UBI device.

All board include config files are adjusted to use this new scheme of
specifying boot MTD/UBI device.

69ca709d0f ubifs: Fix reference count leak in ubifsumount
Original ubifs code was designed that after ubifs_umount() call it is
required to also call ubi_close_volume() which closes underlying UBI
volume. But U-Boot ubifs modification have not implemented it properly
which caused that ubifsumount command contains resource leak. It can be
observed by calling simple sequence of commands:

  => ubi part mtd2
  ubi0: attaching mtd2
  ...
  => ubifsmount ubi0
  => ubifsumount
  Unmounting UBIFS volume rootfs!
  => ubi detach
  ubi0 error: ubi_detach_mtd_dev: ubi0 reference count 1, destroy anyway
  ubi0: detaching mtd2
  ubi0: mtd2 is detached

Fix this issue by calling ubi_close_volume() and mutex_unlock() in
directly in ubifs_umount() function before freeing U-Boot's global
ubifs_sb. And remove duplicate calls of these two functions in remaining
places. Note that when ubifs_umount() is not called then during error
handling is still needed to call ubi_close_volume() and mutex_unlock.

With this change ubifsumount command does not throw that error anymore:

  => ubi part rootfs
  ubi0: attaching mtd2
  ...
  => ubifsmount ubi0
  => ubifsumount
  Unmounting UBIFS volume rootfs!
  => ubi detach
  ubi0: detaching mtd2
  ubi0: mtd2 is detached

3045d61c1c aspeed/spl: Remove OVERLAY from linker script
The generic arm linker script contains this section:

   .bss __rel_dyn_start (OVERLAY) : {
       ...
   }

The (OVERLAY) syntax in the description causes the .bss section to be
included in the NOR area of the image:

 $ objdump -t -j .bss spl/u-boot-spl
  SYMBOL TABLE:
  0000c61c l    d  .bss	00000000 .bss
  0000c640 l     O .bss	00000040 __value.0
  0000c68c g     O .bss	00000000 __bss_end
  0000c61c g     O .bss	00000000 __bss_start
  0000c680 g     O .bss	0000000c stdio_devices

This is what the custom linker script tries to avoid, as the NOR area is
read-only.

Remove the OVERLAY syntax to fix the BSS location:

 $ objdump -t -j .bss spl/u-boot-spl
  SYMBOL TABLE:
  83000000 l    d  .bss	00000000 .bss
  83000000 l     O .bss	00000040 __value.0

  83000040 g     O .bss	0000000c stdio_devices

66900bc254 mmc/aspeed: Probe from controller
The Aspeed SDHCI controller is arranged with some shared control
registers, followed by one or two sets of actual SDHCI registers.

Adjust the driver to probe this controller device first. The driver then
wants to iterate over the child nodes to probe the SDHCI proper:

    ofnode node;

    dev_for_each_subnode(node, parent) {
    	struct udevice *dev;
    	int ret;

    	ret = device_bind_driver_to_node(parent, "aspeed_sdhci",
    					 ofnode_get_name(node),
    					 node, &dev);
    	if (ret)
    		return ret;
    }

However if we did this the sdhci driver would probe twice; once
"naturally" from the device tree and a second time due to this code.

Instead of doing this we can rely on the probe order, where the
controller will be set up before the sdhci devices. A better solution is
preferred.

Select MISC as the controller driver is implemented as a misc device.
