This chip is compatible with the existing driver, except that it uses
BAR2 instead of BAR1 for the I/O memory region. Using this patch I can
use the PCIe ethernet interface on the CompuLab Trimslice to boot from
the network.
Instead of directly calling the low-level invalidate_dcache_range() and
flush_cache() functions, provide thin wrappers that take into account
alignment requirements.
While at it, fix a case where the cache was flushed but should have been
invalidated, two cases where the buffer data was flushed instead of the
descriptor and a missing cache invalidation before reading the packet
data that the NIC just wrote to memory.
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.

Add the __iomem address space marker for the tsec pointers
to struct tsec_mii_mng memory mapped register regions.
This solves the sparse warnings for mixig normal pointers
with __iomem pointers for tsec.
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.
There are several implementation issues for tsec_mcast_addr()
addressed by this patch:
* unmanaged, not portable r/w access to registers; fixed with
setbits_be32()/ clrbits_be32()
* use of volatile pointers
* unnecessary forced cast to u8 for the ether_crc() result
* removed redundant parens
* corrected some comment slips
This fixes the following compiler warnings when activating

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 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.
net: designware: Respect "bus mode" register contents on SW reset
"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.
net: add support for extended registers to mdio command
Some phys (Micrel) have additional registers that can
be accessed using a special sequence. This patch allows
to use standard "mdio" command to accesss these registers.
Some phys (Micrel) has extended registers that must be
accessed in a special way. Add pointers to the phy driver
structure to allow to use these functions with mdio command.
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.
The cache API of SH was changed from dcache_wback_range to flush_dcache_range.
sh-eth uses dcache_wback_range. This patch changes to flush_dcache_range.

malta: use unmapped flash base address
The physical base address of the NOR flash is 0x1e000000

Currently, U-Boot uses the mapped address to access the
flash, which does not work in recent qemu versions.

(mips_malta: correct reading MIPS revision at 0x1fc00010)
writing to the mapped address space causes a CPU exception.

to detect the CFI flash chip.

constant to fix the problem. In order to avoid relocation
problems, also update the CONFIG_SYS_{TEXT,MONITOR}_BASE
constants.
