3177457853 net/phy: Fix the phy id mask of AR8031
The both AR8031 and AR8035 belong to Atheros 803x serial PHY.
So the phy id mask of AR8031 is the same to the phy id mask
of AR8035. The right mask value is 0x4fffff.

This patch has been tested on the P1010 and P1023.

b1690bc39c net: tsec: Fix mac addr setup portability, cleanup
Fix the 32-bit memory access that is not "endianess safe",
i.e. not giving the desired byte layout for LE cpus:
tempval = *((uint *) (tmpbuf + 4)), where 'char tmpbuf[]'.

Free the stack from rendundant local vars:
tmpbuf[] and i.

Use a portable type (u32) for the 32bit tsec register value
holder: tempval.

9c9141fd04 net: tsec: Use portable types and accessors for BDs
Currently, the buffer descriptor (BD) fields cannot be
correctly accessed by a little endian processor.  This
patch fixes the issue by making the access of BDs to be
portable among different cpu architectures.

Use portable data types for the Rx/Tx buffer descriptor
fields.  Use portable I/O accessors to insure that the
big endian BDs are correctly accessed by little endian
cpus too, and to insure proper sync with the H/W.
Removed the redundant RTXBD "volatile" type, as proper
synchronization around BD data accesses is provided by
the I/O accessors now.
The "sparse" tool was also used to verify the correctness
of these changes.

b200204e8e net: tsec: Fix priv pointer in tsec_mcast_addr()
Access to privlist[1] (hardcoded referece to the 2nd tsec's
priv area) is neither correct nor does it make sense in the
current context.  Each tsec dev has access to its own priv
instance only, and hence to its own set of group address
registers (GADDR) to filter multicast addresses.

This fix leads to removal of the unused (faulty) privlist[]
and related global static vars.  Note that mcast() can be
called only after eth_device allocation and init, and hence
after priv area allocation, so dev->priv is correctly
initialized upon mcast() call.

ed102be70f net: designware: Fix alignment of buffer descriptors
It's important that buffer descriptors are aligned in accordance to GMAC
data bus width (32/64/128-bit). It's safe to align to 128-bit (16-bytes)
for every bus width type.

If buffer descriptor is improperly aligned GMAC discards lower bits of
provided address and as a result reads from improper location that
doesn't match expected fields.

Commit ef76025a99 "net: Multiple
updates/enhancements to designware.c" introduced another structure
member "link_printed" right before buffer descriptors while "padding"
member was left untouched. This together with alignment of structure
itself to 16-byte boundary forces buffer descriptoprs always to be
4-byte aligned that causes driver complete disfunction if GMAC bus width
is 64 or 128-bit.

Proposed change makes sure all buffer descriptors are 16-byte (128-bit)
aligned.

4220504767 net/phy: realtek: Fix the PHY ID mask to ensure the correct Realtek PHY is detected
The 'get_phy_driver' code in 'drivers/net/phy/phy.c' uses the following
method to determine which driver is to be loaded for a particular PHY
module:

list_for_each(entry, &phy_drivers) {
	drv = list_entry(entry, struct phy_driver, list);
	if ((drv->uid & drv->mask) == (phy_id & drv->mask))
		return drv;
}

This means that a drv->mask of 0xfffff0 will return incorrect phy driver
for the logic above, even if the drv->uid is anything other than
something ending with a 0x0.

For e.g. if the RTL8211E drv->uid is 0x1cc915 and drv->mask is 0xffffff
and the RTL8211B drv->uid is 0x1cc910 and drv->mask is 0xffffff0, then
the phy driver selected will always be RTL8211B even though the
underlying phy connected on the board is a 8211E module.

This patch fixes this issue.

8426d8b089 buildman: make board selector argument a regex
A common use-case is to build all boards for a particular SoC. This can
be achieved by:

./tools/buildman/buildman -b mainline_dev tegra20

However, when the SoC is a member of a family of SoCs, and each SoC has
a different name, it would be even more useful to build all boards for
every SoC in that family. This currently isn't possible since buildman's
board selection command-line arguments are compared to board definitions
using pure string equality.

To enable this, compare using a regex match instead. This matches
MAKEALL's handling of command-line arguments. This enables:

(all Tegra)
./tools/buildman/buildman -b mainline_dev tegra

(all Tegra)
./tools/buildman/buildman -b mainline_dev '^tegra.*$'

(all Tegra20, Tegra30 boards, but not Tegra114)
./tools/buildman/buildman -b mainline_dev 'tegra[23]'

But ROM code expects the boot-device to be connected to only chip-select[0].
Thus to resolve conflict between NOR and NAND boot. This patch:

3f719069c8 mtd: nand: omap: add CONFIG_NAND_OMAP_ECCSCHEME for selection of ecc-scheme
This patch adds new CONFIG_NAND_OMAP_ECCSCHEME, replacing other distributed
CONFIG_xx used for selecting NAND ecc-schemes.
This patch aims at solving following issues.

1) Currently ecc-scheme is tied to SoC platform, which prevents user to select
   other ecc-schemes also supported in hardware. like;
 - most of OMAP3 SoC platforms use only 1-bit Hamming ecc-scheme, inspite
   the fact that they can use higher ecc-schemes like 8-bit ecc-schemes with
   software based error detection (OMAP_ECC_BCH4_CODE_HW_DETECTION_SW).
 - most of AM33xx SoC plaforms use 8-bit BCH ecc-scheme for now, but hardware
   supports BCH16 ecc-scheme also.

2) Different platforms use different CONFIG_xx to select ecc-schemes, which
   adds confusion for user while migrating platforms.
 - *CONFIG_NAND_OMAP_ELM* which enables ELM hardware engine, selects only
    8-bit BCH ecc-scheme with h/w based error-correction (OMAP_ECC_BCH8_CODE_HW)
    whereas ELM hardware engine supports other ecc-schemes also like; BCH4,
    and BCH16 (in future).
 - *CONFIG_NAND_OMAP_BCH8* selects 8-bit BCH ecc-scheme with s/w based error
    correction (OMAP_ECC_BCH8_CODE_HW_DETECTION_SW).
 - *CONFIG_SPL_NAND_SOFTECC* selects 1-bit Hamming ecc-scheme using s/w library

Thus adding new *CONFIG_NAND_OMAP_ECCSCHEME* de-couples ecc-scheme dependency
on SoC platform and NAND driver. And user can select ecc-scheme independently
foreach board.
However, selection some hardware based ecc-schemes (OMAP_ECC_BCHx_CODE_HW) still
depends on presence of ELM hardware engine on SoC. (Refer doc/README.nand)

d016dc42ce mtd: nand: omap: enable BCH ECC scheme using ELM for generic platform
BCH8_ECC scheme implemented in omap_gpmc.c driver has following favours
+-----------------------------------+-----------------+-----------------+
|ECC Scheme                         | ECC Calculation | Error Detection |
+-----------------------------------+-----------------+-----------------+
|OMAP_ECC_BCH8_CODE_HW              |GPMC             |ELM H/W engine   |
|OMAP_ECC_BCH8_CODE_HW_DETECTION_SW |GPMC             |S/W BCH library  |
+-----------------------------------+-----------------+-----------------+

Current implementation limits the BCH8_CODE_HW only for AM33xx device family.
(using CONFIG_AM33XX). However, other SoC families (like TI81xx) also have
ELM hardware module, and can support ECC error detection using ELM.

This patch
- removes CONFIG_AM33xx
	Thus this driver can be reused by all devices having ELM h/w engine.
- adds omap_select_ecc_scheme()
	A common function to handle ecc-scheme related configurations. This
	can be used both during device-probe and via user-space u-boot commads
	to change ecc-scheme. During device probe ecc-scheme is selected based
	on CONFIG_NAND_OMAP_ELM or CONFIG_NAND_OMAP_BCH8
- enables CONFIG_BCH
	S/W library (lib/bch.c) required by OMAP_ECC_BCHx_CODE_HW_DETECTION_SW
  	is enabled by CONFIG_BCH.
- enables CONFIG_SYS_NAND_ONFI_DETECTION
	for auto-detection of ONFI compliant NAND devices
- updates following README doc
	doc/README.nand
	board/ti/am335x/README
	doc/README.omap3

beba5f04f2 mtd: nand: omap: make am33xx/elm.c as common driver for all OMAPx and AMxxxx platforms
ELM hardware engine which is used for ECC error detection, is present on all
latest OMAP SoC (like OMAP4xxx, OMAP5xxx, DRA7xxx, AM33xx, AM43xx). Thus ELM
driver should be moved to common drivers/mtd/nand/ folder so that all SoC
having on-chip ELM hardware engine can re-use it.
This patch has following changes:
- mv arch/arm/include/asm/arch-am33xx/elm.h arch/arm/include/asm/omap_elm.h
- mv arch/arm/cpu/armv7/am33xx/elm.c drivers/mtd/nand/omap_elm.c
- update Makefiles
- update #include <asm/elm.h>
- add CONFIG_NAND_OMAP_ELM to compile driver/mtd/nand/omap_elm.c
	and include in all board configs using AM33xx SoC platform.
