common/xyzModem.c: Do not use hard-coded address for debug buffer
Under the plethora of #ifdefs, the xyzModem code hid this pearl:
static char *zm_out = (char *) 0x00380000;
This was only enabled when DEBUG is defined, so it's probably why it
went unnoticed for so long. No idea what platform had memory at that
exact location, but the this approach is extremely hacky.
Use a static buffer instead.

ARMv8: add GOT sections to the list of sections copied
Recent Linux distributions (e.g. Debian 9) include cross-compilers for

One key differences between an aarch64-linux-gnu and an aarch64-elf
compiler are the default settings regarding position-independent: with
the aarch64-linux-gnu compiler, the default will create and use the

This change-set adjusts the list of sections copied on ARMv8 to include

* defconfig: rk3399-puma: rename to puma-rk3399
* rockchip: config: rk3399: update defconfigs and rk3399_common
For the RK3399-Q7, we want a default boot-order of SPI -> MMC -> uSD.
This both follows how the BootROM probes devices and is a sane default
for customers in device-personalisation (e.g. it allows for quick and
easy factory programming of unpersonalised devices using an SD card)
and field usage (with customer devices expected to have their firmware
either in SPI or MMC).
However, when probing multiple interfaces (according to the result
from the board_boot_order function), we need to ensure that only valid
FIT images are considered and disable the fallback to assuming that a
raw (binary-only) U-Boot image is loaded (to avoid hangs/crashes from
jumping to random content loaded from devices that are probed, but
don't contain valid image content).
By disabling the SPL_RAW_IMAGE_SUPPORT and SPL_LEGACY_IMAGE_SUPPORT
options, we ensure that raw images (indistinguishable from random
data) are not considered for booting.

These changes add a device-tree describing the board and its

customised boards) has an on-module SPI-flash connected to SPI1.

The SPI5 controller is routed to the Q7 edge connector and provides
general-purpose SPI connectivity for customer base-boards.

rockchip: rk3399: spl: make SPL boot-order configurable via /chosen
The RK3399 does not have any boot selection pins and the BootROM probes
the boot interfaces using the following boot-order:
1. SPI
2. eMMC (sdhci in DTS)
3. SD card (sdmmc in DTS)
4. USB loader
For ease of deployment, the SPL stage should mirror the boot order of
the ROM and use the same probing order (assuming that valid images can
be detected by SPL) unless instructed otherwise. The boot-order can
then be configured via the 'u-boot,spl-boot-order' property in the
chosen-node of the DTS.
While this approach is easily extensible to other boards, it is only
implemented for the RK3399 for now, as the large SRAM on the RK3399
makes this easy to fit the needed infrastructure into SPL and our
production setup already runs with DM, OF_CONTROL and BLK in SPL.
The new boot-order property is expected to be used in conjunction with
FIT images (and all legacy image formats disabled via Kconfig).
A boot-sequence with probing and fallthroughs from SPI via eMMC to SD
card (i.e. &spiflash, &sdhci, &sdmmc) has been validated on the RK3399-Q7.

net: gmac_rockchip: Add support for the RK3399 GMAC
The GMAC in the RK3399 is very similar to the RK3288 variant (i.e. it
is a Designware GMAC core and requires similar configuration as the
RK3288 to switch it to RGMII and set up the TX/RX delays for Gigabit).
The key difference is that the register offsets (within the GRF block)
and bit-offsets (within those registers) used to hold the configuration
differ between the various RK32/33 CPUs.
This change refactors the gmac_rockchip.c driver to use a function
table (selected via driver_data) to factor out these differences. Each
function's implementation then matches the underlying processor.
Some collateral changes are needed in the definitions describing the
bits and offsets in the GRF are needed to prefix each set of symbolic
constants with the SoC name to avoid name clashes... and in doing so,
the shifts for masks and constants have been moved into the header
files for readability (and to make it easier to stay below 80 chars).
