Commit fa9c021632473 ("mx6: add example DTB for mx6qsabreauto") introduced
'imx6q-sabreauto.dts' but it adds no real value as the dts file only contains
the 'model' and 'compatible' strings.
After this commit the final binary is also changed from 'u-boot.imx' to
'u-boot-dtb.imx', which may confuse users.
So revert it until a more complete and useful device tree could be provided.

UART does not use the UART FIFO, but we should also not rely that
the UART FIFO is diabled by default. For instance, when loading
U-Boot using the boot ROMs serial downloader protocol over UART,
FIFO is enabled at U-Boot start time.
This patch disables the RX and TX FIFO, sets back their thresholds
and flushes them.

The status register 1 (S1) is not writeable, hence we should not
write it. In order to clear the RDRF flag we only need to read
the data register.
Also, when stressing U-Boot a lot with serial input, an overflow can
occur which asserts the S1_OR flag (while not asserting the S1_RDRF
flag). To clear this flag we again just need to read the data
register, hence add this flag to the abort conditions for the while
loop.
Insert a compiler barrier to make sure reading the data register
gets executed after reading the status register.

The load region size of EIM-NOR are defined to 0. For this case,
the parameter "imximage_init_loadsize" must be calculated.
The imximage tool implements the calculation in the "imximage_generate"
function, but the following function "imximage_set_header" resets the value
and not calculate. This bug cause some fields of IVT head are not
correct, for example the boot_data and DCD overlay the application area.

The Latency parameters of PL310 Tag RAM latency control register and
Data RAM Latency control register are set in L2 cache enable. And
setting these registers must have PL310 NOT enabled.
But when using Plugin mode boot, the PL310 is enabled by bootrom.
The patch disables the PL310 before applying this setting.

The leds array within struct ventana has space for 3 elements, but the
setup_board_gpio() function tries to set up 4 GPIOs for LEDs. Recent
versions of GCC complain about that:
board/gateworks/gw_ventana/gw_ventana.c: In function 'setup_board_gpio':
board/gateworks/gw_ventana/gw_ventana.c:987:27: warning: iteration 3u invokes undefined behavior [-Waggressive-loop-optimizations]

Fix this by making the upper bound of the loop match the array size.

According to mx53 and mx6 reference manuals:
"The maximum size of the DCD limited to 1768 bytes."
As each DCD entry consists of 8 bytes, we have a total of 1768 / 8 = 221, and
excluding the first entry, which is the header leads to 220 as the maximum
number for DCD size.

Current way of calculation CS0_END field for MMDCx_MDASP register
is problematic because in most cases the user is forced to define
cs_density in an unnatural way: as value - 2, instead of value.
This breaks the abstraction provided by struct mx6_ddr_sysinfo
because the user is forced to be aware of the way the calculation
is performed.

the same powerdown precharge. Currently, mx6_dram_cfg()
configures MMDC for fast pd (MDPDC[7] = 0), and the DRAM for

The IMX6 MMDC calibration registers depend on propagation delay and capacitive
loading between the SoC's MMDC and the DDR3 chips. On the Ventana boards the
board layout varies little in trace-lengths such that propagation delays are
irrelevant thus we can simply things by using calibration values obtained
from various board layouts based on a common SoC and DDR chip configuration.
This eliminates board-model from being needed allowing more flexibility. These
values were tested on a large sample size of Gateworks Ventana boards ranging
in layout, and memory configuration over the entire temperature range supported.

When testing the FEC driver on a mx6solox we noticed that the TDAR bit gets
always cleared prior then the READY bit is cleared in the last BD, which causes
FEC packets reception to always fail.
As explained by Ye Li:
"The TDAR bit is cleared when the descriptors are all out from TX ring, but on
mx6solox we noticed that the READY bit is still not cleared right after TDAR.
These are two distinct signals, and in IC simulation, we found that TDAR always
gets cleared prior than the READY bit of last BD becomes cleared.
In mx6solox, we use a later version of FEC IP. It looks like that this
intrinsic behaviour of TDAR bit has changed in this newer FEC version."
Fix this by polling the READY bit of BD after the TDAR polling, which covers the
mx6solox case and does not harm the other SoCs.
No performance drop has been noticed with this patch applied when testing TFTP
transfers on several boards of different i.mx SoCs.

mx6solox has a requirement for 64 bytes alignment for RX DMA transfer.
Other SoCs work with the standard 32 bytes alignment.
Adjust it accordingly by using 64 bytes aligment in the FEC RX DMA buffers,
which addresses the needs from mx6solox and also works for the other SoCs.
