Recently Freescale (now NXP) received order to make more P2020DS.
It's better have to U-Boot support than digging out old releases.
Changes in v1:
Add back P2020DS, using generic board structure.
Initial patch to adjust DDR speed tables.

This reverts commit 168dcc6cef7a0e13bc52fc8fa8de2866cf4033dc.
Align with changes since P2020DS was removed, including adding
these macros to defconfig
CONFIG_SYS_NS16550
CONFIG_CMD_NET
CONFIG_NETDEVICES
CONFIG_E1000
CONFIG_CMD_DHCP
Remove macros and include from board header file, including
CONFIG_E1000
CONFIG_MTD_NAND_VERIFY_WRITE
CONFIG_SYS_NS16550
config_cmd_default.h
CONFIG_CMD_ELF
CONFIG_CMD_SETEXPR
CONFIG_CMD_NET
Fixed checkpatch errors of exceedding 80 characters, etc.

From: York Sun @ 2016-01-30 22:03 UTC (permalink / raw)
To: u-boot
As old DIMMs are EOL, new DIMMs need some adjustment to the
speed table. It is necessary to separate UDIMM and RDIMM for
DDR3. Verified on iDIMM M3CN-2GSF3C09-G.
Signed-off-by: York Sun <york.sun@nxp.com>

Changes in v1:
Initial patch to adjust DDR speed tables.

I will take this chance to convert P2020DS to use DM. Need some guidance here.
For NS16550, it needs the clock. To keep it simple, let's presume platform data
is used. My trouble is the clock is not unknown at compiling time. It needs to
be updated by checking the board/soc configuration after power up. The clock is
only available after get_clocks() is called in init_sequance. Is there a way I
can update the clocks before the driver is initialized?

See this commit:

Simon,
Thanks for the pointer. I actually noticed this commit but it adds some
confusion to me. Take your code as an example
U_BOOT_DRIVER(serial_ns16550) = {
.name = "serial_tegra20",
.id = UCLASS_SERIAL,
.of_match = tegra_serial_ids,
.ofdata_to_platdata = tegra_serial_ofdata_to_platdata,
.platdata_auto_alloc_size = sizeof(struct ns16550_platdata),
.priv_auto_alloc_size = sizeof(struct NS16550),
.probe = ns16550_serial_probe,
.ops = &ns16550_serial_ops,
};
The name "serial_ns16550" is not directly used anywhere. So I guess you didn't
have to name it as "serial_ns16550", right?
One step forward, if I want to create a new driver, say "fsl_ns16550", I will
have to use ofdata_to_platdata to fill in plat->clock. But for majority powerpc
SoCs, we don't use device tree. We may start to use device tree on new products.
But it is probably not a good idea to force every platform to change.
Is there another way to update plat->clock?

The commit Simon gave was an old one. Now all ns16550 driver has been
unified into one.

Please do not create a new driver for FSL chipset. Does FSL have any
plan to continue maintaining all these PowerPC SoCs in U-Boot? If yes,
I believe the intention is to bring driver model and device tree to
these boards.

You can define CONFIG_SYS_NS16550_CLK to a routine that gets the
correct clock freq at runtime: eg: get_serial_clock()

That's a relief. I don't want to create a new driver just for the clock.

I'd rather to add the device tree step by step, not all at once. And probably
leave some legacy boards behind.

Please explain in detail. I want to go down this path. For non-device tree
platforms (for the time being), doesn't U_BOOT_DEVICES evaluate the platdata at
compiling time? How can I use a routine as the clock for ns16550_platdata?
It is pretty simple for fixed clock, as I am looking at an example
arch/arm/cpu/armv7/am33xx/board.c.

Agreed. We can add device tree and driver model drivers to these
PowerPC boards step by step as long as they are maintained. There is
no need to add them in a bunch. It's easy to convert these PowerPC
boards to driver model, given they share some of the IPs in the new
LayerScape ARM SoCs.

We should add device tree to these platforms. The non-device tree
(U_BOOT_DEVICES) was mainly for some SPL boards which does not have
enough RAM before memory is initialized. I think you may refer to this
patch: http://patchwork.ozlabs.org/patch/561853/

I looked into ls1021atwr earlier, ns16550 driver takes default value
CONFIG_SYS_NS16550_CLK when the device tree doesn't have the clock-frequency
node. It is a smart solution for device-tree enabled platforms.
Even I believe we want to go with device tree for new boards, I don't believe
driver model has to be used with device tree. We have many boards with
sd/spi/nand boot options, including the P2020DS I am trying to bring back.
