For sun4i/sun5i/sun7i boards which set DRAM_ODT_EN=y (which no defconfigs

console: Fix pre-console flushing via cfb_console being very slow
On my A10 OlinuxIno Lime I noticed a huge (5+ seconds) delay coming from
console_init_r. This turns out to be caused by the preconsole buffer flushing
to the cfb_console. The Lime only has a 16 bit memory bus and that is already
heavy used to scan out the 1920x1080 framebuffer.
The problem is that print_pre_console_buffer() was printing the buffer once
character at a time and the cfb_console code then ends up doing a cache-flush
for touched display lines for each character.
This commit fixes this by first building a 0 terminated buffer and then
printing it in one puts() call, avoiding unnecessary cache flushes.
This changes the time for the flush from 5+ seconds to not noticable.
The downside of this approach is that the pre-console buffer needs to fit
on the stack, this is not that much to ask since we are talking about plain
text here. This commit also adjusts the sunxi CONFIG_PRE_CON_BUF_SZ to
actually fit on the stack. Sunxi currently is the only user of the pre-console
code so no other boards need to be adjusted.

Having bit 22 cleared in the PL310 Auxiliary Control register (shared

Shared Non-cacheable reads into Cacheable no-allocate reads.
Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer
corruption.
This was inspired by a patch from Catalin Marinas [1] and also from recent

suggested that bootloaders should initialize the cache.

mx6cuboxi sometimes fails to recognize the Ethernet PHY:
Net: Phy 0 not found
The explanation for this behavior comes from from Rabeeh Khoury:
"The LED_ACT pin on the carrier-one boards had a pull down that
forces the phy address to 0x0; where on CuBox-i and the production
HummingBoard that pin is connected directly to LED that depending
on the pull down strength of the LED it might be sampled as '0' or '1' thus
the phy address might appear as either address 0x0 or 0x4."
"This is AR8035 implementation; in reset stage the LED pin is configured as
input, and pull up/down does matter. In this case it configures the PHY
address.
After reset is deasserted the same LED pin becomes output and then
according to the previous pull/up it should be active high/low"
One way to properly fix this behavior is to place external pull-up/down
resistors in the LED line, but from a software standpoint we can fix it
by telling phy_find_by_mask() to scan the PHY at addresses
0x0 and 0x4.

test: dm: add sandbox PMIC framework tests
This change adds new file to sandbox driver model test environment.
The file is: test/dm/power.c, and it includes tests for PMIC framework,
which includes PMIC uclass and REGULATOR uclass.
All tests are based od Sandbox PMIC emulated device. Some test constants for
this device are defined in the header: include/power/sandbox_pmic.h
PMIC tests includes:
- pmic get - tests, that pmic_get() returns the requested device
- pmic I/O - tests I/O by writing and reading some values to PMIC's registers
and then compares, that the write/read values are equal.
The regulator tests includes:
- Regulator get by devname/platname
- Voltage set/get
- Current set/get
- Enable set/get
- Mode set/get
- Autoset
- List autoset
For the regulator 'get' test, the returned device pointers are compared,
and their names are also compared to the requested one.
Every other test, first sets the given attribute and next try to get it.
The test pass, when the set/get values are equal.

sandbox: add: sandbox PMIC device drivers: I2C emul, pmic, regulator
This commit adds emulation of sandbox PMIC device, which includes:
- PMIC I2C emulation driver
- PMIC I/O driver (UCLASS_PMIC)
- PMIC regulator driver (UCLASS_REGULATOR)
The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes,
which allows using 'i2c md' command with the default count (16).
The sandbox PMIC provides regulators:
- 2x BUCK
- 2x LDO
Each, with adjustable output:
- Enable state
- Voltage
- Current limit (LDO1/BUCK1 only)
- Operation mode (different for BUCK and LDO)
Each attribute has it's own register, beside the enable state, which depends
on operation mode.
The header file: sandbox_pmic.h includes PMIC's default register values,
which are set on i2c pmic emul driver's probe() method.

5. Support DM, but pinctrl is not included. Pinmux setting is still set

6. struct i2c_parms and struct sram_data are removed.
7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist
paramter of bus_i2c_init is modified to i2c index. Add new prototype
i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for

{
if (i2c_bus->index == 0)
force_bus_idle(i2c_pads_info0);
else if (i2c_bus->index == 1)
force_bus_idle(i2c_pads_info1);
else

We maintain an accumulator for time spent reading from SPI flash, since

sunxi: ohci: Add ohci usb host controller support
This commit adds support for the OHCI companion controller, which makes
usb-1 devices directly plugged into to usb root port work.
Note for now this switches usb-keyboard support for sunxi back from int-queue
support to the old interrupt polling method. Adding int-queue support to the
ohci code and switching back to int-queue support is in the works.
