Added d-cache support for zynq_gem.c,
Observed a difference of +0.8 MiB/s when downloading
a file of size of 3007944Bytes.
With d-cache OFF:
----------------
Filename 'uImage'.
Load address: 0x800
Loading: #################################################################

With d-cache ON:

Bytes transferred = 3007944 (2de5c8 hex)
Changes on zynq_gem for d-cache support:
- Tx and Rx buffers are cache-aligned
- Updated logic for invalidating Rx buffers and flushing Tx buffers.
- Tx and Rx BD's are allocated from non-cacheable region.
(When BDs are cached, we don't see a consistent link)
- Use TX BD status intead of txsr status checks.

When an unprogrammed EEPROM is attached to a dm9000, the dm9000 will
come up with a invalid MAC address of ff:ff:ff:ff:ff:ff. Add code that
gets enabled if CONFIG_RANDOM_MACADDR is enabled that generates a random
(and valid) locally administered MAC address that allows the system to
network boot until a real MAC address can be configured.

The e1000 driver expects to always have some kind of non-volatile memory
attached directly to the ethernet controller chip. This means that I would
have to add an additional separate flash chip to my custom board just to
store essentially the MAC address. Since I don't want to do that, this patch
introduces a new config option CONFIG_E1000_NO_NVM. If defined it disables
all accesses to the NVM. I have tested the patch with a 82574 controller.

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.

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.

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.

This solves the sparse warnings for mixig normal pointers with

Remove tsec_t typedef. Define macros as getters of
tsec and mdio register memory regions, for consistent
initialization of various 'regs' fields and also to
manage overly long initialization lines.
Use the __iomem address space marker to address sparse
warnings in tsec.c where IO accessors are used, like:
tsec.c:394:19: warning: incorrect type in argument 1 (different
address spaces)
tsec.c:394:19: expected unsigned int volatile [noderef]
<asn:2>*addr
tsec.c:394:19: got unsigned int *<noident>

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.

In the eth_mcast_join() implementation, eth_current->mcast()

Fix parameter type mismatch for tsec_macst_addr() (tsec.c):
ether_crc() takes a u8 pointer not a u8 value.
mcast() is given a u8 pointer to the multicats mac address.

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 ef76025a99247cdb8f927a2c9f15400678dfb599 "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.

"bus mode" register contains lots of fields and some of them don't
expect to be written with 0 (zero). So since we're only interested in
resetting MAC (which is done with setting the least significant bit of
this register with "0") I believe it's better to modify only 1 bit of
the register.

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.

This delay applies to any data transfer on I2C bus.
For example 1kB data read with per-byte access (which happens if
environment is stored in I2C EEPROM) takes more than 10 seconds.
Moreover data bus driver has to care about bus state and data transfer,
but not about internal states of attached devices.

The endless waiting for a bit to be set can cause a hang, add a timeout
so we prevent such situation. A testcase for such a hang is below. The
testcase assumes a device to be present at address 0x50 and a device to
NOT be present at address 0x42 . Also note that the "sleep 1" induced
delays are imperative for this bug to manifest .
i2c read 0x42 0x0.2 0x10 0x42000000 ; sleep 1 ; \
i2c read 0x50 0x0.2 0x10 0x42000000 ; sleep 1 ; \
i2c read 0x42 0x0.2 0x10 0x42000000
The expected result of the above command is:
Error reading the chip.

While without this patch, we observe a hang in the last read from 0x42
precisely when waiting for this bit to be set.

Current implementation only supports 8 bit word lengths, even though
omap3 can handle anything between 4 and 32.
Update the spi interface to support changing the SPI word length,
and implement it in omap3_spi driver to support the full range of
possible word lengths.
This implementation is backwards compatible by defaulting to the old
behavior of 8 bit word lengths.
Also, it required a change to the omap3_spi non static I/O functions,
but since they are not used anywhere else, no collateral changes are required.
