With of-platdata this driver cannot know the format of the of-platdata
struct, so we cannot use generic code for accessing the of-platdata. Each
SoC that uses this driver will need to set up ns16550's platdata for it.
So don't compile in the generic code.

Add an implementation of this function which mirrors the functions of the
automatic device-tree implementation. This can be used with of-platdata to
create regmaps.

We plan to add a new way of creating a regmap for of-platdata. Move the
allocation code into a separate function so that it can be shared.

Devices which use of-platdata have their own platdata. However, in many
cases the driver will have its own auto-alloced platdata, for use with the
device tree. The ofdata_to_platdata() method converts the device tree
settings to platdata.
With of-platdata we would not normally allocate the platdata since it is
provided by the U_BOOT_DEVICE() declaration. However this is inconvenient
since the of-platdata struct is closely tied to the device tree properties.
It is unlikely to exactly match the platdata needed by the driver.
In fact a useful approach is to declare platdata in the driver like this:
struct r3288_mmc_platdata {
struct dtd_rockchip_rk3288_dw_mshc of_platdata;
/* the 'normal' fields go here */
};
In this case we have dt_platadata available, but the normal fields are not
present, since ofdata_to_platdata() is never called. In fact driver model
doesn't allocate any space for the 'normal' fields, since it sees that there
is already platform data attached to the device.
To make this easier, adjust driver model to allocate the full size of the
struct (i.e. platdata_auto_alloc_size from the driver) and copy in the
of-platdata. This means that when the driver's bind() method is called,
the of-platdata will be present, followed by zero bytes for the empty
'normal field' portion.
A new DM_FLAG_OF_PLATDATA flag is available that indicates that the platdata
came from of-platdata. When the allocation/copy happens, the
DM_FLAG_ALLOC_PDATA flag will be set as well. The dtoc tool is updated to
output the platdata_size field, since U-Boot has no other way of knowing
the size of the of-platdata struct.

PERIPH_ID_SDMMC4(131) is not continous value with PERIPH_ID_SDMMC0(75).
If there is no 'index' property in fdt, then dev_index should be
assigned to dev_id(Peripheral ID).
At this time, dev_index should be "56". It means Exynos SoC has "56"
numbers of DWMMC IP. To prevent this behavior, it needs to check the
maximum device index.

Define a platform data structure for the MPC85XX GPIO driver to allow
use of the driver without device tree. Users should define the GPIO
blocks for their platform like this:
struct mpc85xx_gpio_plat gpio_blocks[] = {
{
.addr = 0x130000,
.ngpios = 32,
},
{
.addr = 0x131000,
.ngpios = 32,
},
};
U_BOOT_DEVICES(my_platform_gpios) = {
{ "gpio_mpc85xx", &gpio_blocks[0] },
{ "gpio_mpc85xx", &gpio_blocks[1] },
};
This is intended to build upon the recent submission of the base
MPC85XX driver from Mario Six. We need to use that new driver
without dts support and this patch gives us that flexibility.
This has been tested on a Freescale T2080 CPU, although only the first
GPIO block.

The driver model conversion for MMC has moved in small steps. The first step
was to have an MMC device (CONFIG_DM_MMC). The second was to use a child
block device (CONFIG_BLK). The final one is to use driver model for MMC
operations (CONFIG_DM_MMC_OP). Add support for this.
The immediate priority is to make all boards that use DM_MMC also use those
other two options. This will allow them to be removed.
