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. - -Signed-off-by: Mathieu Olivari <mathieu@codeaurora.org> ---- - arch/arm/Kconfig | 2 +- - arch/arm/Makefile | 2 ++ - arch/arm/mach-qcom/Makefile.boot | 1 + - 3 files changed, 4 insertions(+), 1 deletion(-) - create mode 100644 arch/arm/mach-qcom/Makefile.boot - ---- a/arch/arm/Kconfig -+++ b/arch/arm/Kconfig -@@ -311,7 +311,7 @@ config ARCH_MULTIPLATFORM - select ARCH_WANT_OPTIONAL_GPIOLIB - select ARM_HAS_SG_CHAIN - select ARM_PATCH_PHYS_VIRT -- select AUTO_ZRELADDR -+ select AUTO_ZRELADDR if !ARCH_QCOM - select CLKSRC_OF - select COMMON_CLK - select GENERIC_CLOCKEVENTS ---- a/arch/arm/Makefile -+++ b/arch/arm/Makefile -@@ -248,9 +248,11 @@ MACHINE := arch/arm/mach-$(word 1,$(mac - else - MACHINE := - endif -+ifeq ($(CONFIG_ARCH_QCOM),) - ifeq ($(CONFIG_ARCH_MULTIPLATFORM),y) - MACHINE := - endif -+endif - - machdirs := $(patsubst %,arch/arm/mach-%/,$(machine-y)) - platdirs := $(patsubst %,arch/arm/plat-%/,$(sort $(plat-y))) ---- /dev/null -+++ b/arch/arm/mach-qcom/Makefile.boot -@@ -0,0 +1 @@ -+zreladdr-y+= 0x42208000 |
