The current SPI clock divider calculation has two problems:
- We use a normal round-down division, which results in a divider
typically being too small, resulting in a too high frequency on the bus.
- The calculaction for the power-of-two divider is very inaccurate, and
again rounds down, which might lead to wild bus frequencies.
This wasn't a real problem so far, since most chips can handle slightly
higher bus frequencies just fine. Also the actual speed was mostly lost
anyway, due to release_bus() reseting the device. And the power-of-2
calculation was probably never used, because it only applies to
frequencies below 47 KHz.
However this will become a problem for the F1C100s support, due to its
much higher base frequency.
Calculate a safe divider correctly (using round-up), and re-use that
value when calculating the power-of-2 value. We also separate the
maximum frequency and the input clock on the way, since they will be
different for the F1C100s.

As George rightfully pointed out [1], the spi-sunxi driver programs the
speed and mode settings only when the respective functions are called,
but this gets lost over a call to release_bus(). That asserts the
reset line, thus forces each SPI register back to its default value.
Adding to that, trying to program SPI_CCR and SPI_TCR might be pointless
in the first place, when the reset line is still asserted (before
claim_bus()), so those setting won't apply most of the time. In reality
I see two nested claim_bus() calls for the first use, so settings between
the two would work (for instance for the initial "sf probe"). However
later on the speed setting is not programmed into the hardware anymore.
So far we get away with that default frequency, because that is a rather
tame 24 MHz, which most SPI flash chips can handle just fine.
Move the actual register programming into a separate function, and use
.set_speed and .set_mode just to set the variables in our priv structure.
Then we only call this new function in claim_bus(), when we are sure
that register accesses actually work and are preserved.

Because the gate arrays are not given explicit sizes, the arrays are

However, only a subset of the CCU clocks are needed by U-Boot. So there
are valid clock specifiers with indexes greater than the size of the

Fix this by checking the identifier against the size of the array.

SPL_DEBUG_UART_BASE") fixed support for setting correct early debug UART
base address in SPL.
But after this commit, output from Marvell A385 BootROM is truncated or
lost and not fully present on serial console.
Debugging this issue showed that BootROM just put bytes into UART HW output
buffer and does not wait until UART HW transmit all characters. U-Boot
ns16550 early debug is initialized very early and during its initialization
is resetting UART HW and flushing remaining transmit buffer (which still
contains BootROM output).
Fix this issue by waiting in init function prior resetting UART HW until
TxEmpty bit in UART Line Status Register is set. TxEmpty is set when all
remaining bytes from HW buffer are transmitted.

With the current code if the board has an ONFI compliant NAND without
support to the get and set features, U-boot returns an ENOTSUP error when
trying to tune the timings which prevents the probe of the device.
Indeed onfi_set_features() return ENOTSUP error if set/get features is not
supported. In the case of timings we should not return ENOTSUP because we
can use the default timings. The NAND is already capable of listening at
its highest supported rate, so we assume in this case that it is fine to
skip the operation.

does not error out if set/get feature is not supported.

The Aspeed SDHCI controller is arranged with some shared control
registers, followed by one or two sets of actual SDHCI registers.
Adjust the driver to probe this controller device first. The driver then
wants to iterate over the child nodes to probe the SDHCI proper:
ofnode node;
dev_for_each_subnode(node, parent) {
struct udevice *dev;
int ret;
ret = device_bind_driver_to_node(parent, "aspeed_sdhci",
ofnode_get_name(node),
node, &dev);
if (ret)
return ret;
}
However if we did this the sdhci driver would probe twice; once
"naturally" from the device tree and a second time due to this code.
Instead of doing this we can rely on the probe order, where the
controller will be set up before the sdhci devices. A better solution is
preferred.
