59370f3fcd net: phy: delay only if reset handler is registered
With commit e3a77218a2 the MII bus is only
reset if a reset handler is registered. If there is no reset handler there
is no need to wait for a device to come out of the reset.

The rxbd is not correctly handled in case of a frame physical error
(FPE) or frame size error (FSE). The rxbd must be cleared and

1a791892dc net: lpc32xx: add RMII phy mode support
LPC32xx MAC and clock control configuration requires some minor quirks
to deal with a phy connected by RMII.

It's worth to mention that the kernel and legacy BSP from NXP sets
SUPP_RESET_RMII == (1 << 11) bit, however the description of this bit is
missing in shared LPC32x0 User Manual UM10326 Rev. 3, July 22, 2011
and in LPC32x0 Draft User Mannual Rev. 00.27, November 20, 2008, also
in my tests an SMSC LAN8700 phy device connected over RMII seems to
work correctly without touching this bit.

Add support of RMII, if CONFIG_RMII is defined, this option is aligned
with a number of boards, which already define the same config value.

23f5db0e26 net: lpc32xx: improve MAC configuration on reset and initialization
This change rearranges general MAC configuration and PHY specific
configuration of MAC registers (duplex mode and speed), before this
change set bits related to PHY configuration in MAC2 and COMMAND
registers are rewritten by the following writing to the registers.

Without the change auto negotiation on boot quite often is not
completed in reasonable time:

  Waiting for PHY auto negotiation to complete......... TIMEOUT !

Additionally MAC1_SOFT_RESET clear bit is removed since it is done in
preceding lpc32xx_eth_initialize() and in lpc32xx_eth_halt(), instead
added missing MCFG_RESET_MII_MGMT on device initialization.

0b830198fb net: davinci_emac: don't teardown inactive rx channel
Tearing down an unitialized rx channel causes a pending address hole
event to be queued. When booting linux it will report this pending

This reverts commit 17da712024.

The i210/i211 do have the SW_FW_SYNC (0x5b5c) register and this is what should
be used when acquiring the semaphore.

I believe the issue that this patch was trying to resolve is now resolved
by properly releasing the semaphore once no longer needed.

8c4585881d dm: serial: Add a REQUIRE_SERIAL_CONSOLE option for boards with no serial port
Currently the serial code assumes that there is always at least one serial
port (and panics / crashes due to null pointer dereferences when there is
none).

This makes it impossible to use u-boot on boards where there is no (debug)
serial port, because e.g. all uart pins are muxed to another function.

This commit adds a CONFIG_REQUIRE_SERIAL_CONSOLE Kconfig option, which
defaults to y (preserving existing behavior), which can be set to n on
such boards to make them work.

This commit only implements this for CONFIG_DM_SERIAL=y configs, as allowing
running without a serial port for CONFIG_DM_SERIAL=n configs is non trivial,
and is not necessary at this moment.

c9f8947e66 sunxi: usb-phy: Never power off the usb ports
USB devices are not really designed to get the power bounced off and on
at them. Esp. USB powered harddisks do not like this.

Currently we power off the USB ports both on a "usb reset" and when
booting the kernel, causing the usb-power to bounce off and then back
on again.

This patch removes the powering off calls, fixing the undesirable power
bouncing.

Note this requires some special handling for the OTG port:
1) We must skip the external vbus check if we've already enabled our own
vbus to avoid false positives
2) If on an usb reset we no longer detect that the id-pin is grounded, turn
off vbus as that means an external vbus may be present now

08eb947004 ddr: altera: sdram: Make sdram_start and sdram_end into u32
Originally, both sdram_start and sdram_end were 64b values. The
sdram_start had no reason for being so, since our address space
is only 32b, so switching sdram_start to u32 is simple.

The sdram_end is a bit more complex, since it can actually be
set to (1 << 32) if someone really wanted to use an SoCFPGA with
4 GiB of DRAM and fixed the code around a little. But, the code
handling the protection rules internally decrements the sdram_end
variable anyway. Thus, instead of calling the code and passing in
the address of the SDRAM end, pass in the address already decremented
