We need to clear the allocated memory explicitly as the included
struct sdhci_host has function pointers. Those are compared to NULL to
test if this (optional) feature is supported. Leaving them undefined let
u-boot jump to arbitrary memory.Signed-off-by: Alexander Stein

Freescale eMMC44 adapter card uses Micron N2M400FDB311A3CF eMMC
memory. According to the silicon datasheet, secure erase timeout
is 600ms. So increase erase timeout value from 250ms to 600ms.Signed-off-by: Yangbo Lu

Timeout interrupt also work for response busy command(R1b) like
cmd38/cmd6. So need to set it accordingly. Current code only
set timeout for data command.Signed-off-by: Kevin Liu

High capacity support is not a host capability, but a device capability
that is queried via the OCR. The flag in the operating conditions
request argument can just be set unconditionally. This matches the Linux
implementation.[panto] Hand merged and renumbering MMC_MODE_DDR_52MHz.

Starting part of device initialization sets the init_in_progress flag
only if the MMC card did not yet come to ready state and needs to continue
polling. If the card is SD or if the MMC card became ready quickly,
the flag is not set and (if using pre-initialization) the starting
phase will be re-executed from mmc_init function.Set the init_in_progress flag in all non-error cases. Also, move flags
setting statements around so that the flags are not set in error paths.
Also, IN_PROGRESS return status becomes unnecessary, so get rid of it.Signed-off-by: Andrew Gabbasov

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
