Nowadays it's preferred to use the generic CONFIG_SERIAL_8250_OMAP

in multi_v7_defconfig and in omap2plus_defconfig, for compatibility
reasons. Let's switch to ttyS2 console, to be sure that standard 8250

Similar behavior can be also achieved by enabling

to rely on that, as it can be disabled or removed after transitional
period.
Right now on DRA7/AM57x platforms the 8250-omap driver is being probed
first, and omap-serial driver is only probed if the first one failed.
It can be seen from uart3 definition in arch/arm/boot/dts/dra7-l4.dtsi:
compatible = "ti,dra742-uart", "ti,omap4-uart";
So the kernel already uses 8250 driver. This change basically allows

compatibility options. Similar discussions [1,2] have started several

net: macb: Fix check for little-endian system in gmac_configure_dma()
Instead of depending on CONFIG_SYS_LITTLE_ENDIAN, we check at runtime
whether underlying system is little-endian or big-endian. This way
we are not dependent on any U-Boot specific OR compiler specific macro
to check system endianness.

Rev. A of the board uses a Spansion S25FL512S_256K serial flash, which
is 64 MB in size and has an erase sector size of 256KB (therefore,
flashing the RCW would erase part of U-Boot).
Rev. B and C of the board use a Spansion S25FL256S1 serial flash, which
is only 32 MB in size but has an erase sector size of 64KB (therefore
the RCW image can be flashed without erasing U-Boot).
To avoid the problems above, the U-Boot base address has been selected
at 0x100000 (the start of the 5th 256KB erase sector), which works for
all board revisions. Actually 0x40000 would have been enough, but
0x100000 is common for all Layerscape devices.
eTSEC3 is connecting directly to SJA1105 via an RGMII fixed-link, but
SJA1105 is currently not supported by uboot. Therefore, eTSEC3 is
disabled.

[Vladimir] Code taken from https://github.com/openil/u-boot (which
itself is mostly copied from ls1021a-iot) and adapted with the following
changes:
- Add a008850 errata workaround
- Converted eTSEC, MMC to DM to avoid all build warnings
- Plugged in distro boot feature, including support for extlinux.conf
- Added defconfig for QSPI boot
- Added the board/freescale/ls1021atsn/README.rst for initial setup
- Increased CONFIG_SYS_MONITOR_LEN so that the SPL malloc pool does not
get overwritten during copying of the u-boot.bin payload from MMC to
DDR. Acked-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

[Vladimir] Made the following changes:
- Added 'status = "disabled";' for all Ethernet ports in ls1021a.dtsi
- Fixed the confusion between the SGMII/TBI PCS for enet0 and enet1 -
a mistake ported over from Linux. Each SGMII PCS lies on the private
MDIO bus of the interface (and the RGMII enet2 has no SGMII PCS).
- Added CONFIG_DM_ETH to all ls1021atwr_* defconfigs
- Completely removed non-DM_ETH support from ls1021atwr
- Changed "compatible" string from "fsl,tsec-mdio" to "fsl,etsec2-mdio"
and from "fsl,tsec" to "fsl,etsec2" to match Linux

net: tsec: Change compatible strings to match Linux
In the case of the tsec network driver, so far there has been no
mainline user of DM_ETH where the DT bindings get used.
In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string
was made up for the documentation, but there is no mainline code that
parses the "compatible" property anyway.
In both cases, there are no DT blobs that contain the old strings.
So change the documentation to "fsl,etsec2" for the Ethernet ports and
"fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also
uses, at least for LS1021A. More compatible strings can be added once
other (PowerPC) SoCs are migrated to DM_ETH.
The current ls1021a.dtsi doesn't match what was documented for the MDIO
buses anyway (the "compatible" is "gianfar" currently). This will be
fixed in the next patch.

net: tsec: Fix offset of MDIO registers for DM_ETH
By convention, the eTSEC MDIO controller nodes are defined in DT at
0x2d24000 and 0x2d50000, but actually U-Boot does not touch the
interrupt portion of the register map (MDIO_IEVENTM, MDIO_IMASKM,
MDIO_EMAPM).
That leaves only the MDIO bus registers (MDIO_MIIMCFG, MDIO_MIIMCOM,
MDIO_MIIMADD, MDIO_MIIMADD, MDIO_MIIMCON, MDIO_MIIMSTAT) which start at
the 0x520 offset.
So shift the DT-defined register map by the offset of MDIO_MIIMCFG when
mapping the MDIO bus registers.
