[U-Boot] [PATCH] ppc4xx: Clear all potentially pending exceptions in MCSR
by Stefan Roese 20 Nov '08

20 Nov '08

This is needed on Canyonlands which still has an exception pending while running relocate_code(). This leads to a failure after trap_init() is moved to the top of board_init_r(). --- cpu/ppc4xx/start.S | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) diff --git a/cpu/ppc4xx/start.S b/cpu/ppc4xx/start.S index 882ef21..84d7a28 100644 --- a/cpu/ppc4xx/start.S +++ b/cpu/ppc4xx/start.S @@ -1440,6 +1440,10 @@ relocate_code: dccci 0,0 /* Invalidate data cache, now no longer our stack */ sync isync + + /* Clear all potential pending exceptions */ + mfspr r1,mcsr + mtspr mcsr,r1 #ifdef CONFIG_SYS_TLB_FOR_BOOT_FLASH addi r1,r0,CONFIG_SYS_TLB_FOR_BOOT_FLASH /* Use defined TLB */ #else -- 1.6.0.4

[U-Boot] [PATCH] ppc4xx: Changed 460EX/GT OCM TLB and internal SRAM initialization
by Dave Mitchell 20 Nov '08

20 Nov '08

Expanded OCM TLB to allow access to 64K OCM as well as 256K of internal SRAM. Adjusted internal SRAM initialization to match updated user manual recommendation.

[U-Boot] [PATCH] ppc4xx: Added ppc4xx-isram.h for internal SRAM and L2 cache DCRs
by Dave Mitchell 20 Nov '08

20 Nov '08

Added include/asm-ppc/ppc4xx-isram.h and moved internal SRAM and L2 cache DCRs from ppc440.h to this new header. Also converted these DCR defines from lowercase to uppercase and modified referencing modules to use them.

Re: [U-Boot] mini-pci wireless driver
by Lance Zhang 20 Nov '08

20 Nov '08

I am sorry about the format. My questions are: How can I support wireless network card on U Boot? I want to implement a wlan mini-pci driver, But when I see U Boot source tree, there is no codes related to wireless, do you have any suggestion on how to add wireless support on U Boot? Or is there any U Boot branches that have already implemented wireless extension on U boot?

[U-Boot] [PATCH] mpc83xx: Improve the performance of DDR memory
by Dave Liu 20 Nov '08

20 Nov '08

From: Howard Gregory <Greg.Howard(a)freescale.com> modify the CAS timings. my understanding is that these settings decrease various wait times in the DDR interface. Because these wait times are in clock cycles, and the DDR clock on the 8315 RDB runs slower than on some other 83xx platforms, we can dial down these values without a problem, thereby decreasing the latency of memory a little.

[U-Boot] [PATCH v3] mpc83xx: New board support SIMPC8313
by Ron Madrid 20 Nov '08

20 Nov '08

This patch will create a new board, SIMPC8313, from Sheldon Instruments. This board boots from NAND devices and is configureable for either large or small page devices. The board supports non-soldered DDR2, one ethernet port, a Marvell 88E1118 PHY, and PCI host support. The board also has a FPGA connected to the eLBC providing glue logic to a TMS320C67xx DSP.
