for them the calculated highest DRAM address is 0xafffffff, which is
exactly in the gap and thus not usable.
Fix this by iterating over all DRAM banks and tracking the remaining

dm: core: Deal with a wrinkle with linker lists
When every member of a linker list is aligned by the compiler, we can no
longer rely on the sizeof of the struct to determine the number of
entries.
For example, if the struct size is 0x90 but every entry is aligned to 0xa0
by the compiler, the linker list entries takes more space in memory and
the calculation of the number of entries is incorrect. For example, we may
see 0x12 entries when there are only 0x11.
This is a real problem. There may be a general solution, although I cannot
currently think of one. So far it only bites with OF_PLATDATA_RT which
creates a pointer to each entry of the 'struct udevice' linker_list. This
does not happen without that option, so it only affects SPL.
Work around it by manually calculating the aligned size of struct udevice,
then using that for the n_ent calculation.

rockchip: serial: restyle the serial_rockchip.c driver
The ns16550.c driver has the following conditions for .of_match:
CONFIG_IS_ENABLED(OF_REAL)
For Rockchip SoCs with TPL/SPL and platform data that need serial
support the serial_rockchip.c driver was made. It copies this data
and then calls ns16550_serial_probe(). With the addition of yet an other
SoC type this driver is in need for a little restyle.
Simplify struct rockchip_uart_plat and add extra SoCs with
DM_DRIVER_ALIAS(). Return -ENODEV when the ns16550.c driver
probe function is available.

rockchip: mmc: rockchip_dw_mmc: add rk3066/rk3188 support
The Rockchip SoCs rk3066/rk3188 have MMC DT nodes
with as compatible string "rockchip,rk2928-dw-mshc".
Add OF_PLATDATA support to the existing driver with
help of a DM_DRIVER_ALIAS.
This type needs a permanent enabled fifo.
The other Rockchip SoCs always have the property
"u-boot,spl-fifo-mode" in the MMC DT nodes,
because MMC to SRAM can't do DMA.
Make this property a requirement for MMC OF_PLATDATA
structures. The property "fifo-mode" must be added
for all other compile modes.

rockchip: mmc: rockchip_dw_mmc: fix ciu clock index
The document rockchip-dw-mshc.yaml decribes a maximum of 4 clocks.
In the rockchip_dw_mmc driver the clock name in use was "fixed"
to "ciu" with index 1, but later reverted back to index 0.
The clock drivers can handle both, but the calling driver
should submit correct data as a standard practice.
Fix the "ciu" clock index by setting it back to 1.

rockchip: timer: add OF_PLATDATA support for dw-apb-timer
The Rockchip rk3066 SoC has 3 dw-apb-timer nodes.
U-boot is compiled with OF_PLATDATA TPL/SPL options,
so add OF_PLATDATA support for the dw-apb-timer.
Also change driver name to be able to compile with
U-boot scripts. No reset OF_PLATDATA support was added,
because the rk3066 nodes don't need/have them.

rockchip: tpl: use IS_ENABLED for timer_init() call condition
Not all Rockchip SoC models use the ARM arch timer.
Call the function timer_init() only when
CONFIG_SYS_ARCH_TIMER is available.
Use the call condition IS_ENABLED to increase
build coverage and make the code easier to read.
