d2d9bdfcf9 spl: saveenv: adding saveenv support in SPL
By default saveenv option is not supported for SPL. This patch
enable the support for save environment variable for SPL build.

Enable save environment support in SPL after setenv. By default
the saveenv option is not provided in SPL, but some boards need
this support in 'Falcon' boot, where SPL need to boot from
different images based on environment variable set by OS. For
example OS may set "reboot_image" environment variable to
"recovery" inorder to boot recovery image by SPL. The SPL read
"reboot_image" and act accordingly and change the reboot_image
to default mode using setenv and save the environemnt.

f53c4e4bbd mmc: tegra: priv struct and naming cleanup
struct mmc_host is a Tegra-specific structure, but the name implies it's
something defined by core MMC code, which is confusing. Rename it to
struct tegra_mmc_priv to make its purpose more obvious. The new name is
also more appropriate for a DM driver private data structure, which will
be relevant later in this series.

Nothing needs access to this type except the MMC driver itself. Move the
definition into the driver C file.

Make sure all Tegra MMC functions are named tegra_mmc_*. Even though
they're all static, it's useful to have good naming so that symbol tables
are easy to interpret. A few functions aren't renamed by this patch since
they'll be deleted by a subsequent patch in this series.

6138d5b682 mmc: tegra: don't use periph_id in pad_init_mmc()
The MMC driver will soon be converted to use standard clock/reset APIs,
and so the periph_id field in the MMC device priv struct will disappear.
Rework the implementation of pad_init_mmc() to rely on this; using the
device register address is a much more direct test anyway.

67748a73b1 mmc: tegra: use correct alias for SDHCI/MMC nodes
The Tegra MMC driver currently honors "sdhci" entries in /aliases. The
MMC core however uses "mmc" entries in /aliases. This difference will be
relevant once the Tegra MMC driver is converted to DM, and the MMC core
handles alias lookups. To avoid issues during that conversion, fix the
Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC
core does.

It's nicer to see this:

dwmmc@ff0f0000: 1 (eMMC)

than this:

dwmmc@ff0c0000: 0dwmmc@ff0f0000: 1 (eMMC)

With the former, it's much clearer which mmc devices are on.

Because of the time difference between the two calls of get_timer(),
the timeout detected after the loop may not be true.

1483151e84 mmc: fsl: introduce wp_enable
Introudce wp_enable. To check WPSPL, wp_enable needs to be set
to 1 in board code.

Take i.MX6UL for example, for some boards, they do not use WP singal,
so they does not configure USDHC1_WP_SELECT_INPUT, and its default
value is 0(GPIO1_IO02). However GPIO1_IO02 is muxed for i2c usage and
SION bit set. So USDHC controller can always get wp signal and WPSPL
shows write protect and blocks driver continuing. This is not what
we want to see, so add wp_enable, and if set to 0, just omit the
WPSPL checking and this does not effect normal working of usdhc
controller.

If wp-gpios is provided in dts, wp_enable is set to 1, otherwise 0.

The USDHC moves the 4 clock bits CARD_CLK_SOFT_EN, IPG_PERCLK_SOFT_EN,
HCLK_SOFT_EN, and IPG_CLK_SOFT_EN from sysctl register to vendorspec
register. The driver uses RSTA to replace the clock gate off
operation. But this is not a good solution because:
1. when using RSTA, we should wait this bit to clear by itself. This is not
   implemeneted in the code.
2. After RSTA is set, it is recommended that the Host Driver reset the
   external card and reinitialize it.

So in this patch, we change to use the vendorspec registers for these bits
operation.

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

39f633320c mmc: tegra: add basic Tegra186 support
Tegra186's MMC controller needs to be explicitly identified. Add another
compatible value for it.

Tegra186 will use an entirely different clock/reset control mechanism to
existing chips, and will use standard clock/reset APIs rather than the
existing Tegra-specific custom APIs. The driver support for that isn't
ready yet, so simply disable all clock/reset usage if compiling for
Tegra186. This must happen at compile time rather than run-time since the
custom APIs won't even be compiled in on Tegra186. In the long term, the
plan would be to convert the existing custom APIs to standard APIs and get
rid of the ifdefs completely.

The system's main eMMC will work without any clock/reset support, since
the firmware will have already initialized the controller in order to
load U-Boot. Hence the driver is useful even in this apparently crippled
state.

Support Driver Model for fsl esdhc driver.

1. Introduce a new structure struct fsl_esdhc_priv
2. Refactor fsl_esdhc_initialize which is originally used by board code.
   - Introduce fsl_esdhc_init to be common usage for DM and non-DM
   - Introduce fsl_esdhc_cfg_to_priv to build the bridge for non-DM part.
   - The original API for board code is still there, but we use
     'fsl_esdhc_cfg_to_priv' and 'fsl_esdhc_init' to serve it.
3. All the functions are changed to use 'struct fsl_esdhc_priv', except
   fsl_esdhc_initialize.
4. Since clk driver is not implemented, use mxc_get_clock to geth
   the clk and fill 'priv->sdhc_clk'.

873cc1d777 mmc: store hwpart in the block device
This will allow us to have multiple block device structs each referring
to the same eMMC device, yet different HW partitions.

For now, there is still a single block device per eMMC device. As before,
this block device always accesses whichever HW partition was most recently
selected. Clients wishing to make use of multiple block devices referring
to different HW partitions can simply take a copy of this block device
once it points at the correct HW partition, and use each one as they wish.
This feature will be used by the next patch.

In the future, perhaps get_device() could be enhanced to return a
dynamically allocated block device struct, to avoid the client needing to
copy it in order to maintain multiple block devices. However, this would
require all users to be updated to free those block device structs at some
point, which is rather a large change.

Most callers of mmc_switch_part() wish to permanently switch the default
MMC block device's HW partition. Enhance mmc_switch_part() so that it does
this. This removes the need for callers to do this. However,
common/env_mmc.c needs to save and restore the current HW partition. Make
it do this more explicitly.

Replace use of mmc_switch_part() with mmc_select_hwpart() in order to
remove duplicate code that skips the call if that HW partition is already
selected.

The SD Card Association Physical Layer Simplified Specification also

The Linux kernel distinguishes between secure (bit 31 set) and

The low four bits of the SYSCTL register are reserved on the USDHC
controller on i.MX6 and i.MX7 processors, but are used for clocking
operations on earlier models.

Guard against their usage by hiding the bit mask macros on those

These bits are used to prevent glitches when changing clocks on
i.MX35 et al. Use the RSTA bit instead for i.MX6 and i.MX7.

>From the i.MX6DQ RM:
	To prevent possible glitch on the card clock, clear the
	FRC_SDCLK_ON bit when changing clock divisor value(SDCLKFS
	or DVS in System Control Register) or setting RSTA bit.
