This set of patches adds support for Samsung Exynos4210-based boards NURI and
SMDKC210.
Tested on Linux kernel v3.x series.
Usage:
"-smp 2" option is mandatory for now.
Linux kernel v3.x configured with exynos4_defconfig can be used for boards
models testing with rootfs
on initrd.
To enable support of framebuffer in kernel, enable Samsung S3C framebuffer
driver in kernel configuration.
Note: at present time (26.01.2012) Samsung S3C framebuffer support in
mainline kernel is broken. This
problem will be solved soon by Samsung kernel developers. People interested
in enabling framebuffer right
now can patch Linux kernel source files a bit to fix S3C framebuffer
support:
- in array init_clocks_off (file arch/arm/mach-exynos/clock.c) for a member
with .devname = "exynos4-fb.0"
replace .name from "fimd" to "lcd";
- for framebuffer support on nuri board you need to additionally change
file arch/arm/mach-exynos/common.c:
add include file
"#include <linux/dma-mapping.h>"
and add string
init_consistent_dma_size(SZ_2M + SZ_4M);
at the very beginning of function "void __init exynos4_map_io(void)".
To enable support of ethernet on smdkc210 board, enable SMSC LAN911x/LAN921x
families
embedded ethernet driver in Linux kernel configuration file.
Note: NURI board does not have ethernet adapter and currently has no net
support.
Example usage:
Boot smdkc210 board with root filesystem on NFS disc.
# qemu-system-arm -kernel ./zImage -append "ip=dhcp root=/dev/nfs
nfsroot=10.0.2.2:/srv/nfs/ rw rootwait" -M smdkc210 -smp 2
Boot smdkc210 board with root filesystem on NFS disc and serial port #0
redirected to terminal
# qemu-system-arm -kernel ./zImage -append "console=ttySAC0,115200n8 ip=dhcp
root=/dev/nfs nfsroot=10.0.2.2:/srv/nfs/ rw " -serial stdio -M smdkc210 -smp 2
Boot NURI with rootfs on inird and serial port #0 redirected to terminal
# qemu-system-arm -kernel ./zImage -append "console=ttySAC0,115200n8
root=/dev/ram rw " -serial stdio -M nuri -smp 2 -initrd ./rootfs.ext2
Changelog:
v9->v10
- hw/lan9118.c: fixed migration-breaking bug in previous patch version;
- hw/exynos4210_pmu.c: we do not waste space for non-existing registers in PMU
state anymore;
non-existing registers are now RAZ/WI;
added vmstate structure;
v8->v9
- exynos4210.c: secondary cpu bootloader memory region allocation is removed
(it resides in already allocated IROM),
removed hack memory region for secondary CPU boot loader (PMU
device added).
added l2x0 cache controller
- exynos4210_pmu.c: PMU registers modelling device added to emulation. It is
needed since PMU contains
INFORM5 register which is used to boot the secondary CPUs.
- exynos4_boards.c: indentation fix
- exynos4210_uart.c: indentation fix, BREAK event handling code added, fixed
size of allocated registers region
- exynos4210_gic.c: number of IRQs passed to gic_init() due to last mainline
update.
- lan9118.: added VMSTATE fields due to last mainline update.
v7->v8
- exynos4_boards.c: lack of spaces fix
- exynos4210_gic.c: lack of spaces fix
- exynos4210_combiner.c: lack of spaces fix
- exynos4210_uart.c: lack of spaces fix, indentation fix
- exynos4210_mct.c: ULL suffix fix
v6->v7
- exynos4210_pwm.c: added usage of "ptimer.h"
- exynos4210_mct.c: added usage of "ptimer.h"
v5->v6
- arm_boot.c, vexpress.c, realview.c: board should specify smp_bootreg_addr if
its ncpu > 1
- patch order changed, "boot secondary CPU" is included in "exynos boards"
patch.
- exynos4210_mct.c: usage of UINTX_MAX, removed excessive property list, fixed
indentation,
fixed comments
- exynos4210_pwm.c: spaces and brakcets in macros, removed excessive property
list,
fixed indentation,
- exynos4210_combiner.c: removed excessive reset, fixed indentation, fixed
comments
- exynos4210_gic.c: fixed indentation, fixed syntax
- exynos4210_uart.c: fixed indentation, fixed syntax
- exynos4210.c: fixed comments
- Makefile.target: removed "\"
- hw/exynos4210_fimd.c: rebased against current master: all manipulation with
physical pages are dropped and
replaced with new memory API functions;
added three new members to winow's state:
MemoryRegionSection to describe section
of system RAM containing current framebuffer, host
pointer to framebuffer data and
framebuffer length;
mapping of framebuffer now performed only on
framebuffer settings change
instead on every display update;
bytes swap in uint64 variable now performed with
standard QEMU bswap64 function;
blencon register type changed to uint32_t;
fixed incorrect spelling of "palette" word;
if ... else statements in exynos4210_fimd_read() and
exynos4210_fimd_write() are
replaced with switch() {} statement.
v4->v5
- hw/exynos4210_gic.c: Use memory aliases for CPU interface and Distributer.
Excessive RW functions are removed.
- hw/exynos4210_pwm.c and hw/exynos4210_mct.c: Saving of timers added.
- hw/exynos4210_uart.c: VMSTATE version_id fixed.
v3->v4
- Split Exynos SOC and boards.
- Temporary removed SD and CMU support to post later.
- Lan9118 remarks took into account.
- Secondary CPU bootloader remarks took into account.
- PWM remarks took into account.
- UART remarks took into account.
v2->v3
- Reverted hw/arm_gic.c modification
- Added IRQ Gate to Exynos4210 board.
