Hi,
Isn't evb short for evaluation board? That makes board board then. ;)

You'll need to implement dram_init_banksize() to avoid "DRAM: 0 Bytes"?
I doesn't get "DRAM: 0 Bytes", I get "DRAM: 2 GiB"
Okay, not sure what the difference between our patches was then.
But please remember to leave a white line before and after your inline
comments or they are really hard to spot among a huge quote!
Note that this happens among others in Thunderbird when writing in HTML
mode but sending as text mode. (That's why I force my account to always
use text mode also for composing, which works around that.)

Please make this a Kconfig selection to avoid confusion.
OK, actually, I want to know how to decide where to put the CONFIG_
MACROs, we have defconfig, common config for soc, and common config
for board.
I don't have a definitive answer, but defconfig is per board, so if
something is always needed for the SoC it should go into the
mach-rockchip or rk3399 Kconfig, I think.
Whether that applies here ... Simon?
People add "CONFIG_SYS_NS16550=y" in defconfig, so I will do that too.

Yes, the content for CONFIG_ROCKCHIP_COMMON has been removed,

Move size into evb config? (commit message says up to ~4GB)
Possibly move banks too or is it always 1?
Rockchip evb is is combined by a mainboard and a daughter board
which daughter board usually including rk3399, DRAM, eMMC, the
DRAM could be 2GB or 4GB. The rk3399 SoC can support up to 4G-128M,
but for U-Boot, we don't actually using so large space, maybe 128MB is
enough.
So we prefer to using a 2GB config for compatible, which also easy to setup
to MMU table.
I don't see a problem with configuring less DRAM than available, but it
will become an issue once there are boards or TV boxes with 1 GB or
less. Therefore it's safer to place the SDRAM_BANK_SIZE into the evb's
config to force new boards to set it to a sane value.
Moved the SDRAM_BANK_SIZE to evb's config in V5.
The CONFIG_NR_DRAM_BANKS is always 1 for Rockchip SoCs.
How much RAM does the DDR blob enable? If it's more than 128 MB then we
What do your mean by "How much RAM does the DDR blob enable?"?
Thanks,
- Kever
should use the full 2GB or whatever here, since it affects loading of
kernels and operation of EFI applications such as GRUB (which will
allocate from top of RAM).
Note to self: In my patch I seem not to set SDRAM_BANK_SIZE at all,
which may be why I was seeing "DRAM: 0 Bytes".
Thanks,
Andreas
