Note:
arch/powerpc/cpu/mpc8260/Makefile is originally like follows:
---<snip>---
START = start.o kgdb.o
COBJS = traps.o serial_smc.o serial_scc.o cpu.o cpu_init.o speed.o \
---<snip>---
COBJS-$(CONFIG_ETHER_ON_SCC) = ether_scc.o
---<snip>---
$(LIB): $(OBJS)
$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)
The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)'
is weird.
kbdg.o is not included in $(OBJS) but linked into $(LIB)
and $(LIB) is not dependent on kgdb.o.
(Broken dependency tracking)
So,
START = start.o kgdb.o
shoud have been
START = start.o
SOBJS = kgdb.o
That is why this commit adds kgdb.o to obj-y, not to extra-y.

into DDR, then jump to it to begin execution.
The SPL's size is sizeable, the maximum size must not exceed the size of L2
SRAM. It initializes the DDR through SPD code, and copys final uboot image
to DDR. So there are two stage uboot images:
* spl_boot, 96KB size. The env variables are copied to L2 SRAM, so that
ddr spd code can get the interleaving mode setting in env. It loads
final uboot image from offset 96KB.
* final uboot image, size is variable depends on the functions enabled.

This workaround is for the erratum I2C A004447. Device reference
manual provides a scheme that allows the I2C master controller
to generate nine SCL pulses, which enable an I2C slave device
that held SDA low to release SDA. However, due to this erratum,
this scheme no longer works. In addition, when I2C is used as
a source of the PBL, the state machine is not able to recover.
At the same time, delete the reduplicative definition of SVR_VER
and SVR_REV. The SVR_REV is the low 8 bits rather than the low 16
bits of svr. And we use the CONFIG_SYS_FSL_A004447_SVR_REV macro
instead of hard-code value 0x10, 0x11 and 0x20.
The CONFIG_SYS_FSL_A004447_SVR_REV = 0x00 represents that one

When a board (slave) boots from SRIO/PCIE, it would get the instructions
from a remote board (master) by SRIO/PCIE interface, and the slave's
u-boot image should be built with the
SYS_TEXT_BASE=0xFFF80000;
So the u-boot of the slave should avoid the NOR_BOOT branch at the
booting stage.
For example, when a P2041RDB boots from SRIO/PCIE, it will set TLB
entry 15 from base address "CONFIG_SYS_MONITOR_BASE & 0xffc00000",
and with the 4M size as the boot window in NOR_BOOT branch. Because
the CONFIG_SYS_MONITOR_BASE = CONFIG_SYS_TEXT_BASE = 0xFFF80000, so
the TLB entry will be from base address 0xffc00000 and with 4M size.
Then the u-boot will set TLB entry 14 from base address
"CONFIG_SYS_INIT_RAM_ADDR", and with the 16K size as the initial
stack window. For the P2041RDB platform, the CONFIG_SYS_INIT_RAM_ADDR
= 0xffd00000. So the TLB entry 14 and 15 will be in confliction.
There will be right TLB entries configurations when avoid the
NOR_BOOT branch and set the boot window from 0xfff00000 with 1M
size space.

So, add new symbols CONFIG_SYS_MPC85XX_NO_RESETVEC for this application.

and the segment .bootpg is placed in the previous 4K of the segment .text.
