[U-Boot] [PATCH] ppc4xx: Fix UART baudrate setup by FDT
by Matthias Fuchs 07 Jan '09

07 Jan '09

On ppc4xx platforms __ft_board_setup updates clock-frequency properties of all ns16550 compatible UARTs. This is not a good idea when those UARTs are external discrete UARTs that are not clocked by some internal clocks. So any external clock value in the DTB is overwritten and those UARTs will not be setup correctly by the Linux kernel. This patch uses the approach from fdt_fixup_ethernet(). Only UART nodes that have a serial* alias are updated. --- common/fdt_support.c | 20 ++++++++++++++++++++ cpu/ppc4xx/fdt.c | 3 ++- include/fdt_support.h | 1 + 3 files changed, 23 insertions(+), 1 deletions(-) diff --git a/common/fdt_support.c b/common/fdt_support.c index 5a83bca..99d4c3f 100644 --- a/common/fdt_support.c +++ b/common/fdt_support.c @@ -454,6 +454,26 @@ void fdt_fixup_ethernet(void *fdt) } } +void fdt_fixup_serial(void *fdt) +{ + int node, i; + char serial[10]; + const char *path; + + node = fdt_path_offset(fdt, "/aliases"); + if (node < 0) + return; + + i = 0; + while (1) { + sprintf(serial, "serial%d", i++); + path = fdt_getprop(fdt, node, serial, NULL); + if (path == NULL) + break; + do_fixup_by_path_u32(fdt, path, "clock-frequency", gd->uart_clk, 1); + } +} + #ifdef CONFIG_HAS_FSL_DR_USB void fdt_fixup_dr_usb(void *blob, bd_t *bd) { diff --git a/cpu/ppc4xx/fdt.c b/cpu/ppc4xx/fdt.c index c55e1cf..5b267d1 100644 --- a/cpu/ppc4xx/fdt.c +++ b/cpu/ppc4xx/fdt.c @@ -134,8 +134,9 @@ void ft_cpu_setup(void *blob, bd_t *bd) /* * Setup all baudrates for the UARTs + * Note: aliases in the dts are required for this */ - do_fixup_by_compat_u32(blob, "ns16550", "clock-frequency", gd->uart_clk, 1); + fdt_fixup_serial(blob); /* * Fixup all ethernet nodes diff --git a/include/fdt_support.h b/include/fdt_support.h index 6062df9..bf3df60 100644 --- a/include/fdt_support.h +++ b/include/fdt_support.h @@ -49,6 +49,7 @@ void do_fixup_by_compat_u32(void *fdt, const char *compat, const char *prop, u32 val, int create); int fdt_fixup_memory(void *blob, u64 start, u64 size); void fdt_fixup_ethernet(void *fdt); +void fdt_fixup_serial(void *fdt); int fdt_find_and_setprop(void *fdt, const char *node, const char *prop, const void *val, int len, int create); void fdt_fixup_qe_firmware(void *fdt); -- 1.5.6.3

[U-Boot] [PATCH] Blackfin: set proper LDRFLAGS for parallel booting LDRs
by Mike Frysinger 07 Jan '09

07 Jan '09

In order to boot an LDR out of parallel flash, the ldr utility needs a few flags to tell it to generate the right header.

[U-Boot] Jffs2 spanning across multiple flash parts
by Bill Sehnert 06 Jan '09

06 Jan '09

I'm stuck in configuring my board for using u-boot. I have multiple nor flash parts that make up my JFFS2 filesystem, but I can't seem to configure U-boot to scan all the parts for the filesystem. It looks like the jffs2 system is looking to a flash partition. and flash partition fits within a flash part. It doesn't seem like I can configure a partition to span across multiple parts. Is that correct? Is there a way to configure the 'mtdparts' to work with multiple parts or am I about to embark on writing a new feature? I can't change how the JFFS2 system is configured on the flash parts. When the linux system boots up, it all works. I just need a way for u-boot to scan the entire flash filesystem to look for the kernel and root filesystem. thanks bill -- Bill Sehnert Sun Microsystems, Inc. 500 Eldorado Boulevard MS: UBRM05-381 Broomfield, CO 80021 Voice: 303-272-6829 Fax: 303-272-6555 Email: william.sehnert(a)sun.com
