Subject: [PATCH RFC 0/5] Mapped kernel support for Broadcom XLP
Date: Fri, 9 May 2014 20:58:20 +0530 [thread overview]
Message-ID: <1399649304-25856-1-git-send-email-jchandra@broadcom.com> (raw)
This patchset adds support for loading a XLR/XLP kernel compiled with a
CKSEG2 load address.
The changes are to:
- move the existing MAPPED_KERNEL option from sgi-ip27 to common config
- Add a plat_mem_fixup function to arch_mem_init which will allow
the platform to calculate the kernel wired TLB entries and save
them so that all the CPUs can set them up at boot.
- Update PAGE_OFFSET, MAP_BASE and MODULE_START when mapped kernel
is enabled.
- Update compressed kernel code to generate the final executable in
KSEG0 and map the load address of the embedded kernel before loading
it.
- Use wired entries of sizes 256M/1G/4G to map the available memory on
XLP9xx and XLP2xx
Comments and suggestions welcome.
JC.
