power-domain: fix hang in endless loop on i.MX8

Currently when booting the kernel on i.MX8 U-Boot hangs in an
endless loop when switching off dma, connectivity or lsio power
domains during device removal. It hapens first when removing
gpio0 (gpio@5d080000) device, here its power domain device
'lsio_gpio0' is obtained for switching off power. Since the
obtained 'lsio_gpio0' device is removed afterwards, its power
domain is also switched off and here the parent power domain
device 'lsio_power_domain' is optained for switching off the
power. Thereafter, when the obtained 'lsio_power_domain' is
removed, device_remove() removes its first child 'lsio_gpio0'.
During this child removal the 'lsio_power_domain' device is
obtained again for switching and when removing it later,
the same child removal is repeated, so we are stuck in an
endless loop. Below is a snippet from dm tree on i.MX8QXP
for better illustration of the DM devices relationship:

 Class     Index  Probed  Driver                Name

4 years agophy: Add support for the NC-SI protocol
Samuel Mendoza-Jonas [Tue, 18 Jun 2019 01:37:17 +0000 (11:37 +1000)]
phy: Add support for the NC-SI protocol

This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.

NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).

This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).

The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.

serial: ns16550: Move PCI access from ofdata_to_platdata() to probe()

Currently the ofdata_to_platdata() method calls dev_read_addr_pci(),
which potentially accesses the parent PCI bus. If this happens before
the parent PCI bus is probed the resulting address will be wrong.

This behavior was triggered by commit 82de42fa1468 ("dm: core:
Allocate parent data separate from probing parent").

According to a comment in drivers/pci/pci-uclass.c [1] accessing
the PCI parent bus in ofdata_to_platdata() is not allowed, and the
access should be moved to the probe() function.

Move the call to dev_read_addr_pci() and the related handling of the
'addr' value from the ofdata_to_platdata() to its own function,
which is then called from the probe() method.

While moving the code, the comment /* try Processor Local Bus device
first */ was dropped. It was initially added with commit 3db886a5bf38
("serial: ns16550: Support ns16550 compatible pci uart devices") and
later made obsolete with commit 33c215af4b9d ("dm: pci: Add a function
to read a PCI BAR").

[1] Comment in drivers/pci/pci-uclass.c:
"A common cause of this problem is that this function is called in the
ofdata_to_platdata() method of @dev. Accessing the PCI bus in that
method is not allowed, since it has not yet been probed. To fix this,

efi_loader: Implement FileLoad2 for initramfs loading

Following kernel's proposal for an arch-agnostic initrd loading
mechanism [1] let's implement the U-boot counterpart.
This new approach has a number of advantages compared to what we did up
to now. The file is loaded into memory only when requested limiting the
area of TOCTOU attacks. Users will be allowed to place the initramfs
file on any u-boot accessible partition instead of just the ESP one.
Finally this is an attempt of a generic interface across architectures
in the linux kernel so it makes sense to support that.

The file location is intentionally only supported as a config option
argument(CONFIG_EFI_INITRD_FILESPEC), in an effort to enhance security.
Although U-boot is not responsible for verifying the integrity of the
initramfs, we can enhance the offered security by only accepting a
built-in option, which will be naturally verified by UEFI Secure Boot.
This can easily change in the future if needed and configure that via ENV
or UEFI variable.

mtd: nand: Fix on-die ecc issues in arasan_nfc driver

Fixed wrong enumeration of nand_config structure. Added chip select
function before reading the nand chip for maf/dev id's, without this
unable to access id's from some of the micron chips. Also added a
print statement to identify if a nand flash is using on-die ecc.

versal: drivers: clk: Fix invalid clock name queries

The clock driver makes EEMI call to get the name of invalid clk
when executing versal_get_clock_info() function. This results in
error messages.
Added check for validating clock before saving clock attribute and
calling versal_pm_clock_get_name() in versal_get_clock_info() function.

arm: zynq: zybo z7: fix SPL uart init bitrate

The board uses 100 MHz clock for UART bitrate generator,
but is configured as 50 MHz on defconfig.

This produces wrong console output.
The first message, "Debug uart enabled" is received as:
"������b"

Fix the issue by configuring the correct clock for the
UART baudrate generator

arm: zynq: zybo z7: fix MIO init issue

The board has two push button connected to MIO pins
50 and 51, which have a pull-down resistor and are
connected to 1.8V when pressed.

These two pins are wrongly initialized with internal
pull-up enabled so they are reported as 1 all the time
with no change when pressed.

Disable the internal pull-up to fix the issue.
