 AFAIKT there is no SPL. U-Boot is loaded by BL3-1 also in the U-Boot
 shipped by amlogic.

The only thing I can think of is a shitty queueing by the UART driver
/ hardware.

 The eth_designware line (twice, if counting "No ma") is due to what Tom

How does that explain the incomplete "No ma"?

You're right, Hardkernel's version is without SPL, too.

Still I wonder about that "No ma" (after the DRAM line).

I found a commit renaming BL3-0 to SCP_BL2, but no mention of BL3-0-1
beyond Hardkernel and this patchset.

Note that the offsets for BL30[1] are shown differently.

On current master with these four patches merged, should I expect to see
any output after BL31? o.O

Note that the README is outdated in that Hardkernel now has sources for
fip_create and no binary any more. I've verified that the behavior is
the same when using the binary and the self-compiled tool. Last output:

P.S. The upstream arm-trusted-firmware fip_create tool doesn't know
about --bl30 and --bl301 btw, anyone any insights?

Good timing.  I've got this locally and just need to finish my unit
tests before I can merge.  But, due to the DM PR I've had to disable eth
as you'll need to address GPIO for this platform next.  Thanks!

[U-Boot] [PATCH v7 0/4] Amlogic Meson GXBaby and ODROID-C2 support

[Beniamino Galvani]

Hi,

this series adds a very basic support for Amlogic S905 SoC (GXBaby)
and for the ODROID-C2 board [1], and is based on u-boot sources
available from the board vendor [2]. At the moment the only supported
devices are the integrated UART and Ethernet adapter.

Changes since v6:
 - documented ARCH_MESON Kconfig entry

Changes since v5:
 - used default CONFIG_SYS_BAUDRATE_TABLE
 - removed check for CONFIG_IDENT_STRING

Changes since v4:
 - added patch to implement generic PSCI reset
 - used min() macro from linux/kernel.h

Changes since v3:
 - designware eth: added check that buffer addresses are in first 4GiB
   as suggested by Marek (and thus removed the ack tags)
 - consolidated pinmux and gpio macros
 - used get_unaligned_be64() to avoid alignment faults in dram_init()
 - uint32_t -> u32 in serial_meson.c
 - implemented reboot and read from e-fuse through secure monitor

Changes since v2:
 - squashed all platform patches into a single one
 - got rid of additional non-upstream DTS node for ethernet
 - improved board README
 - added macros for SoC registers fields

Changes since v1:
 - updated DTS files from Linux kernel
 - added Ethernet support
 - first 16MiB of RAM are now marked as unavailable; this seems to
   be required to successfully boot Linux
 - fixed typo in config file
