Subject: [PATCH 60/69] HACK: arch: arm: force ZRELADDR on arch-qcom
|
|
|
|
ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
|
|
on most ARM architectures. This automatically calculate ZRELADDR by
|
|
masking PHYS_OFFSET with 0xf8000000.
|
|
|
|
However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
|
|
network accelerators, and the bootloader removes this section from the
|
|
layout passed from the ATAGS (when used).
|
|
|
|
For newer bootloader, when DT is used, this is not a problem, we just
|
|
reserve this memory in the device tree. But if the bootloader doesn't
|
|
have DT support, then ATAGS have to be used. In this case, the ARM
|
|
decompressor will position the kernel in this low mem, which will not be
|
|
in the RAM section mapped by the bootloader, which means the kernel will
|
|
freeze in the middle of the boot process trying to map the memory.
|
|
|
|
As a work around, this patch allows disabling AUTO_ZRELADDR when
|
|
ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
|
|
which don't support device-tree, which is the case on certain early
|
|
IPQ806x based designs.
