The current comments are confusing. We don't actually bind a generic device
when the device tree has no information. We try to scan available PCI
drivers. Update the comments to reflect this.

At present pci_mmc_init() does not correctly use the PCI function since the
list it passes is not terminated. The array size passed to pci_mmc_init() is
actually not used correctly. Fix this and adjust the pci_mmc_init() to scan
all available MMC devices.
Adjust this code to use the new driver model PCI API.
This should move over to the new MMC uclass at some point.

Use the driver model version of the function to find the BAR. This updates
the fdtdec function, of which ns16550 is the only user.
The fdtdec_get_pci_bdf() function is dropped for several reasons:
- with driver model we should use 'struct udevice *' rather than passing the
device tree offset explicitly
- there are no other users in the tree
- the function parses for information which is already available in the PCI
device structure (specifically struct pci_child_platdata which is available
at dev_get_parent_platdata(dev)

Most driver model PCI functions have a dm_ prefix. At some point, when the
old code is converted to driver model and the old functions are removed, we
will drop that prefix.
For consistency, we should use the dm_ prefix for all driver model
functions. Update pci_bus_find_bdf() accordingly.

Introduced in 45b4773 (net/arp: account for ARP delay, avoid duplicate packets on timeout)
Check the arp timeout and adjust the timeout start time before the call
to eth_recv() so that the sandbox driver has the opportunity to adjust
the sandbox timer after the new start time has been recorded.
Also, change the adjustment amount by 11 seconds instead of exactly the
10 seconds that the ping timout is expecting since the timeout check is
looking for the time elapsed to be greater than but not equal to the
specified delay.

Override the default name_to_gpio() function with one that
accepts strings of the form bank:pin. If a colon is present
in the provided name, it behaves like the default version.
This lets the "gpio" command work with sane names rather than
requiring the user to enter the bank/pin composite in decimal.

Commit 08ad9b068afb88 (" ar8031: modify the config func of ar8031 to
ar8021_config") selected 'ar8021_config' as the configuration function
for AR8031.
The correct would be to use 'ar8035_config' instead as AR8031/AR8035
have the same programming model and even share the same phy driver
in the linux kernel: drivers/net/phy/at803x.c.
Tested on a mx6qsabresd and wandboard, which now can work without
any PHY setup code in the board files.

Table 41 of the JEDEC standard for eMMC says that bit 31 of
the command argument is obsolete when issuing the ERASE
command (CMD38) on page 115 of this document:
http://www.jedec.org/sites/default/files/docs/jesd84-B45.pdf
The SD Card Association Physical Layer Simplified Specification also
makes no mention of the use of bit 31.
https://www.sdcard.org/downloads/pls/part1_410.pdf
The Linux kernel distinguishes between secure (bit 31 set) and
non-secure erase, and this patch copies the macro names from
include/linux/mmc/core.h.

This could avoid executing the code that only applies to i.MX platforms.
The bus_i2c_init() is called before relocation and will assgin value
to a static variable. If U-Boot is then still running in a flash
device, it's theoretically not allowed to write data to flash without
an erasing operation. For i.MX platforms, the U-Boot is always running
in DDR.
Actually it causes asynchronous error when the ARM64 system error
report is enabled and the flash write protect is set.

The low four bits of the SYSCTL register are reserved on the USDHC
controller on i.MX6 and i.MX7 processors, but are used for clocking
operations on earlier models.
Guard against their usage by hiding the bit mask macros on those
processors.
These bits are used to prevent glitches when changing clocks on
i.MX35 et al. Use the RSTA bit instead for i.MX6 and i.MX7.
>From the i.MX6DQ RM:
To prevent possible glitch on the card clock, clear the
FRC_SDCLK_ON bit when changing clock divisor value(SDCLKFS
or DVS in System Control Register) or setting RSTA bit.

The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot
puts a 0 based port number into the register. The reason the 0 based port
number apparently works can probably be taken from the USB 2.0 spec:
8.4.2.2 Start-Split Transaction Token
... The host must correctly set the port field for single and multiple TT
hub implementations. A single TT hub implementation *may ignore* the port
field.
Actually, as far as I understand, a multi TT hub defaults to single TT
(bAlternateSetting: 0) until switched via SetInterface, so even "port 42"
would work.
The change was verified by hardcoding the port number to a wrong value,
SPLIT transactions kept working (although using a DWC2 instead of MUSB).
Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608
Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub,
the latter single TT only.
