15a2acdf85 common: miiphyutil: Work and report phy address in hex in mdio cmd
It is confusing that mdio commands work and report phy id as
decimal value when mii is working with hex values.

For example:
ZynqMP> mdio list
gem:
21 - TI DP83867 <--> ethernet@ff0e0000
ZynqMP> mdio read ethernet@ff0e0000 0
Reading from bus gem
PHY at address 21:
0 - 0x1140
ZynqMP> mii dump 21 0
Incorrect PHY address. Range should be 0-31
...
ZynqMP> mii dump 15
0.     (1140)                 -- PHY control register --
  (8000:0000) 0.15    =     0    reset

U-Boot normally takes hex values that's why this patch is changing mdio
command to handle hex instead of changing mii command to handle decimal
values.

6c59363004 MIPS: add handling for generic and EJTAG exceptions
Add exception handlers for generic and EJTAG exceptions. Most of
the assembly code is imported from Linux kernel and adapted to U-Boot.
The exception vector table will be reserved above the stack before
U-Boot is relocated. The exception handlers will be installed and

Generic exceptions are handled by showing a CPU register dump similar
to Linux kernel. For example:

EJTAG exceptions are checked for SDBBP and delegated to the SDBBP handler

This could be extended in the future to handle semi-hosting according to

0405092bd2 arm: mx6: specify SPL padding
Specify standard padding for payload to 68KB. This is derived from
the maximum header size plus maximum SPL size. It matches the
already defined offset for SD/eMMC devices (69KB) too. This allows
to use the u-boot-with-spl.imx build target to generate a directly
flashable image which can be flashed using:

  dd if=u-boot-with-spl.imx of=/dev/mmcblk0 bs=512 skip=2

While the patch has been created with SD/eMMC in mind, this also
works with other boot media. The board file needs to configure the
media specific (absolute) payload offset accordingly. Especially
the IVT offset is boot media specific and can be retrieved from the
reference manual (Table 8-25. Image Vector Table Offset and Initial
Load Region Size). For NAND boot a define like this should do the
job:

 #define CONFIG_SYS_NAND_U_BOOT_OFFS (SPL_PAD_TO + 0x400)
