Add option to set spi controller clock frequency via device tree
using standard clock bindings.
Define dw_spi_get_clk function as 'weak' as some targets
(like SOCFPGA_GEN5 and SOCFPGA_ARRIA10) don't use standard clock API
and implement dw_spi_get_clk their own way in their clock manager.
Get rid of clock_manager.h include as we don't use
cm_get_spi_controller_clk_hz function anymore. (we use redefined
dw_spi_get_clk in SOCFPGA clock managers instead)

When clock is enabling, it's assigned to 0 as mmc->clock.
Then it can't initialize any card.
Fix to assign to correct clock value as mmc->cfg->f_min or f_max.

Make flash writes 32 bit aligned by using bounce buffers to deal with
non 32 bit aligned buffers.
This is required because as per TI K2G TRM[1], the external master is
only permitted to issue 32-bit data interface writes until the last word
of an indirect transfer. Otherwise indirect writes is known to fail
sometimes.

This reverts commit 57897c13de03ac0136d64641a3eab526c6810387.
Using bounce_buf.c to handle non-DMA alignment problems is bad as
bounce_buf.c does cache manipulations which is not required. Therefore

This reverts commit b63b46313ed29e9b0c36b3d6b9407f6eade40c8f.
This commit changed cadence_qspi_apb to use bouncebuf.c, which invalidates
the data cache after reading. This is meant for dma transfers only and
breaks the cadence_qspi driver which copies via cpu only: data that is
copied by the cpu is in cache only and the cache invalidation at the end
throws away this data.

Erratum NO. FE-9144572: The device SPI interface supports frequencies of
up to 50 MHz. However, due to this erratum, when the device core clock
is 250 MHz and the SPI interfaces is configured for 50MHz SPI clock and
CPOL=CPHA=1 there might occur data corruption on reads from the SPI
device.
Implement the workaround by setting the TMISO_SAMPLE value to 0x2
in the timing1 register.

The hash command function were not flushing the dcache before passing data
to CAAM/DMA and not invalidating the dcache when getting data back.
Due the data cache incoherency, HW accelerated hash commands used to fail
with CAAM errors like "Invalid KEY Command".
Check if pbuf and pout buffers are properly aligned to the cache line size
and flush/invalidate the memory regions to address this issue.
This solution is based in a previous work from Clemens Gruber in
commit 598e9dccc75d ("crypto/fsl: fix BLOB encapsulation and
decapsulation")

Patch queue for efi - 2018-01-23
This time around we have a lot of EFI patches from Heinrich.
Highlights are:
- Allow EFI applications to register as drivers
- Allow exposure of U-Boot block devices from an EFI payload
- Compatibility improvements
|
|
This patch provides
* a uclass for EFI drivers
* a EFI driver for block devices
For each EFI driver the uclass
* creates a handle
* adds the driver binding protocol
The uclass provides the bind, start, and stop entry points for the driver
binding protocol.
In bind() and stop() it checks if the controller implements the protocol
supported by the EFI driver. In the start() function it calls the bind()
function of the EFI driver. In the stop() function it destroys the child
controllers.
The EFI block driver binds to controllers implementing the block io
protocol.
When the bind function of the EFI block driver is called it creates a
new U-Boot block device. It installs child handles for all partitions and
installs the simple file protocol on these.
The read and write functions of the EFI block driver delegate calls to the
controller that it is bound to.
A usage example is as following:
U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and
exposes a handle with the block IO protocol. It calls ConnectController.
Now the EFI block driver installs the partitions with the simple file
protocol.
iPXE uses the simple file protocol to load Grub or the Linux Kernel.

Commit 4f425280fa71 ("mmc: fsl_esdhc: Allow all supported prescaler
values") made it possible to set SYSCTL.SDCLKFS to 0 in SDR mode on
i.MX, thus bypassing the SD clock frequency prescaler, in order to be
able to get higher SD clock frequencies in some contexts. However, that
commit missed the fact that this value is illegal on the eSDHCv3
instance of the i.MX53. This seems to be the only exception on i.MX,
this value being legal even for the eSDHCv2 instances of the i.MX53.
Fix this issue by changing the minimum prescaler value for the single
instance of the i.MX53 eSDHCv3 controller.

mmc_of_parse() in U-Boot is a pussy helper; it sets cfg->f_max to
52MHz even if DT does not provide "max-frequency" at all. This can
overwrite cfg->f_max that may have been set to a reasonable default.
As the DT binding says, "max-frequency" is an optional property.
Do nothing if DT does not specify it. This is the behavior of
mmc_of_parse() in Linux.

dev_read_u32_default() always returns something even when the property
is missing. So, it is impossible to do nothing in the case. One
solution is to use ofnode_read_u32() instead, but adding dev_read_u32()
will be helpful.
BTW, Linux has an equvalent function, device_property_read_u32();
it is clearer that it reads a property. I cannot understand the
behavior of dev_read_u32() from its name.
