The polling loops in sd_send_op_cond and mmc_complete_op_cond functions
check the ready flag state at the end of the loop, that is after executing
a delay inside the loop, which, in case of exiting with no error,
is not needed. Also, one of these loops, as well as the loop
in mmc_send_status, have the delay just before exiting on timeout
conditions.Restructure all these loops to check the respective conditions before making
a delay for the next loop pass, and to appropriately exit without the delay.Signed-off-by: Andrew Gabbasov

Some MMC cards come to ready state quite quickly, so that the respective
flag appears to be set in mmc_send_op_cond already. In this case trying
to continue polling the card with CMD1 in mmc_complete_op_cond is incorrect
and may lead to unpredictable results. So check the flag before polling
and skip it appropriately.Signed-off-by: Andrew Gabbasov

The previous change to use 'ocr' structure field for storing send_op_cond
command response also stopped using command response directly
outside of mmc_send_op_cond_iter(). Now it becomes possible to use
command structure in mmc_send_op_cond_iter() locally, removing a necessity
to pass it as an argument from the caller.Signed-off-by: Andrew Gabbasov
-
The 'op_cond_response' field in mmc structure contains the response
from the last SEND_OP_COND MMC command while making iterational
polling of the card. Later it is copied to 'ocr' field, designed
to contain the OCR register value, which is actually the same
response from the same command. So, these fields have actually
the same data, just in different time periods. It's easier to use
the same 'ocr' field in both cases at once, without temporary using
of the 'op_cond_response' field.Signed-off-by: Andrew Gabbasov

We are about to change the location for ps7_init files, breaking the
current work-flows. It is good time to drop the legacy ps7_init.c/h
support.Going forward, please use ps7_init_gpl.c/h all the time.
If you are still using old Xilinx tools that are only able to
generate ps7_init.c/h, rename them into ps7_init_gpl.c/h.Signed-off-by: Masahiro Yamada

The PicoZed is a System-on-Module board which is marketed as part of
the ZedBoard/MicroZed/etc. collection. It includes a Zynq-7000
processor.This patch adds support that covers all the variants of the PicoZed
including the SKUs with Z7010/Z7020 and Z7015/Z7030 Zynq chips. This
patch set however only covers support for the System-on-Module and does
not cover any extra components that are available on carrier boards
(except those that are fanned out of the module itself).More information on this board, its variants and available carrier
boards is available at: http://zedboard.org/product/picozedSigned-off-by: Nathan Rossi

These functions now rely on uclass_find_first/next_device() and assume that
they will either return failure (-ve error code) or a device. In fact,
coming to the end of a list is not considered failure and they return 0
in that case.The logic to deal with this was replaced in commit acb9ca2a with just using
uclass_get_device_tail(). Add back the missing logic. This bug was
caught by unit tests but since they were broken for other reasons at the
time, this was not noticed.Signed-off-by: Simon Glass

Upto now flash sector_size is assigned from params which isn't
necessarily a sector size from vendor, so based on the SECT_*
flags from flash_params the erase_size will compute and it will
become the sector_size finally.Bug report (from Bin Meng):

With SPI flash moving to driver model, commit fbb0991 "dm: Convert
spi_flash_probe() and 'sf probe' to use driver model" ignored the
SST flash-specific write op (byte program & word program), which
actually broke the SST flash from wroking.This commit makes SST flash work again under driver model, by adding
SST flash-specific handling in the spi_flash_std_write().Signed-off-by: Bin Meng
