arm64: zynqmp: Enable booting to ATF
U-Boot is now able to boot to ARM Trusted Firmware (ATF). The boot
flow is SPL(EL3) loads ATF and full u-boot and jump to ATF(EL3) which

enable it in this defconfig.
To generate an image that triggers this booting flow, you need to pass

ARM: dts: zynq: Add generic compatible string for I2C EEPROM
The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.

than the 256kb allocated to it.
The MCR3000 board is equipped with an AM29LV160DB boot flash which
is organised as follows:
- One 16kb block
- Two 8kb block
- One 32kb block
- Thirty one 64kb blocks
At the time being, u-boot is a single piece occupying the 256 first
kbytes, then the environment is stored in the following 64kb block
The environment being quite tiny, we save one 64kb block by embedding
the environment in the first 8kb block, hence allowing to increase
the monitor size to 320kb.

common: env_embedded: allow fine placement of environment object
Commit 7653942b10e9e ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.
This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:
This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:
