The WAKEUP_X pins are always an input no matter the pinmux mode.
However, the 18th bit that typical configures a pin as an input is
considered reserved for the WAKEUP_X pins. Therefore, for any WAKEUP
pin remove any configuration that sets that pin as an input. Since
those pins are only inputs remove any output configuration from those
pins.Signed-off-by: Franklin S Cooper Jr

This reverts commit b5a8694cf6a0f2ac504e16e3068b967f3ecc8700.
This patch was incorrectly setting the 18th bit of the padconf register
which is reserved.

WAKEUP2 is used as a gpio input for the touch screen controller's interrupt
output signal. It was incorrect to set it as an output in the first place.This is valid for both the OSD panel that uses the EDT FT5506 touchscreen
controller and the LG panel that uses the LDC3001 touchscreen controller.Signed-off-by: Franklin S Cooper Jr

CONFIG_SPL_NET_VCI_STRING is available only with BOOTP. So if
CMD_DHCP is enabled for SPL in usb ether boot, it will not pass
the right vendor name and failing to download the right file.
Also all the net CMD_* are not required in SPL builds. So defining
these only for non-SPL builds.Reported-by: Yan Liu

Currently when phy device is created the link variable is
initialized to 1 which denoted phy link is already up. On a power
reset there is no issue as phy status register link status will
not be set, so phy auto negotiate will be started. But when a cpu
reset is issued (ex: dra72x-evm) phy's link status bit is already
set which leads to assume that link is already setup in
genphy_update_link() initial check which results in ehternet not
working. So do not assume that link is already up and on phy
device create set link to zero. This is verified on dra72x-evm.Reported-by: Franklin S Cooper Jr

If EMIF is idle for certain amount of DDR cycles, EMIF will put the
DDR in self refresh mode to save power if EMIF_PWR_MGMT_CTRL register
is programmed. And also before entering suspend-resume ddr needs to
be put in self-refresh. Linux kernel does not program this register
before entering suspend and relies on u-boot setting.

DRA72x processor variants are single core and it does not export ACP[1].
Hence, we have no source for generating an external snoop requests which
appear to be key to the deadlock in DRA72x design.Since we build the same image for DRA74x and DRA72x platforms, lets
runtime detect and disable the workaround (in favor of performance) on
DRA72x platforms.[1] http://infocenter.arm.com/help/topic/com.arm.doc.ddi0438i/BABIAJAG.html

Add workaround for Cortex-A15 ARM erratum 801819 which says in summary
that "A livelock can occur in the L2 cache arbitration that might
prevent a snoop from completing. Under certain conditions this can
cause the system to deadlock. "Recommended workaround is as follows:
Do both of the following:1) Do not use the write-back no-allocate memory type.
2) Do not issue write-back cacheable stores at any time when the cache
is disabled (SCTLR.C=0) and the MMU is enabled (SCTLR.M=1). Because it
is implementation defined whether cacheable stores update the cache when
the cache is disabled it is not expected that any portable code will
execute cacheable stores when the cache is disabled.For implementations of Cortex-A15 configured without the “L2 arbitration
register slice” option (typically one or two core systems), you must
also do the following:3) Disable write-streaming in each CPU by setting ACTLR[28:25] = 0b1111
So, we provide an option to disable write streaming on OMAP5 and DRA7.
It is a rare condition to occur and may be enabled selectively based
on platform acceptance of risk.Applies to: A15 revisions r2p0, r2p1, r2p2, r2p3 or r2p4 and REVIDR[3]
is set to 0.Note: certain unicore SoCs *might* not have REVIDR[3] not set, but
might not meet the condition for the erratum to occur when they donot
have ACP (Accelerator Coherency Port) hooked to ACE (AXI Coherency
Extensions). Such SoCs will need the work around handled in the SoC
specific manner, since there is no ARM generic manner to detect such
configurations.Based on ARM errata Document revision 18.0 (22 Nov 2013)

DP83865 ethernet phy used on DRA74x-evm is quirky and the datasheet
provided IODELAY values for standard RGMII phys do not work.Silicon Revision(SR) 2.0 provides an alternative bit configuration
that allows us to do a "gross adjustment" to launch the data off a
different internal clock edge. Manual IO Delay overrides are still
necessary to fine tune the clock-to-data delays. This is a necessary
workaround for the quirky ethernet Phy we have on the platform.NOTE: SMA registers are spare "kitchen sink" registers that does
contain bits for other workaround as necessary as well. Hence the
control for the same is introduced in a generic SoC specific, board
generic location.Signed-off-by: Nishanth Menon

For am43xx_rtconly_evm_defconfig, the bootloader indicates support for
RTC-Only modes by writing a magic number into RTC scratch register
which kernel PM code will then clear and then write back again if
RTC-Only mode entry is desired. If no PM code is loaded in the kernel,
this magic number will not get cleared and then be detected again
by the bootloader on a warm reboot, indicating an RTC+DDR resume event
and causing the bootloader to attempt to jump to the resume address in
RTC scratch register 0, which is invalid.Add a check to prevent jumping to address 0 if the scratch register is
not properly programmed, otherwise warm reboot will not work on am437x
if no PM is loaded in the kernel.Signed-off-by: Dave Gerlach
