When I activate bootstage on ARMV7 architecture with platform

But in the init sequence, the first bootstage fucntion is called

ARM: zynq: Replace dram_init* functions with board_init_f safe ones
The dram_init* functions for the zynq board are not safe for use from
the board_init_f stage due to its use of the 'tmp' static variable.
This incorrect use of a static variable was causing rare issues where
the dram_init function would overwrite some parts the __rel_dyn section
which caused obscure failures.
Using the zynq_zybo configuration, U-Boot would generate the following
error during image load. This was caused due to dram_init overwriting
the relocations for the "image" variable within the do_bootm function.
Out of coincidence the un-initialized memory has a compression type
which is the same as the value for the relocation type R_ARM_RELATIVE.
Uncompressing Invalid Image ... Unimplemented compression type 23
It should be noted that this is just one way the issue could surface,
other cases my not be observed in normal boot flow.
This change removes the existing code and copies the implementation of
the dram_init and dram_init_banksize from the

functions does not use static variables and behaves the same (reading

The problem is that when SoCFPGA performs warm reset, it checks the
addresses 0x40..0x4b in SRAM for a valid preloader signature and
header checksum. If those are found, it jumps to address 0x4c or
0x50 (this is unclear). These addresses are populated by the first
few instructions of arch/arm/cpu/armv7/start.S:
Without this patch, the CPU will enter the code at 0xffff004c or
0xffff0050 , at which point the value of r0 and r1 registers is
undefined. Moreover, jumping directly to the preloader entry point
at address 0xffff0000 will also fail, because address 0xffff004.
is invalid and contains the preloader magic.
Add BOOT0 hook which reserves the area at offset 0x40..0x5f and
populates offset 0x50 with jump to the entry point. This way, the
preloader signature is stored in reserved space and can not corrupt
the SPL code.

fsl/ddr: Add erratum_a009942_check_cpo and clean related erratum
- add additional function erratum_a009942_check_cpo to check if the
board needs tuning CPO calibration for optimal setting.
- move ERRATUM_A009942(with revision to check cpo_sample option) from
fsl_ddr_gen4.c to ctrl_regs.c for reuse on all DDR4/DDR3 parts.
- move ERRATUM_A008378 from fsl_ddr_gen4.c to ctrl_regs.c
- remove obsolete ERRATUM_A004934 which is replaced with ERRATUM_A009942.

travis-ci: Build mvebu boards (arm & aarch64) in separate job
Its easier to watch the output of the build process when the platforms
specific boards are grouped in a separate job. This patch adds a job
for all mvebu boards (arm and aarch64).
