mpc832x: add support for the mpc8321 based suvd3 board

2011-04-29T22:44:29Z

- serial console on UART1 - Ethernet RMII over UCC4 - PHY SMSC LAN8700 - 64MB Flash - 128 MB DDR2 RAM - I2C - bootcount This board is similiar to the kmeter1 (8360) board, so common config options are extracted into the include/configs/km83xx-common.h file.

Revert "PowerPC: Add support for -msingle-pic-base"

2011-04-20T20:11:21Z

This reverts commit 39768f7715ed637ef02f49fc7de664cc1aaf14b3. Reson: it breaks a number of boards with embedded environment as the code size grows in some places.

PowerPC: Add support for -msingle-pic-base

2011-04-11T19:38:47Z

-msingle-pic-base is a new gcc option for ppc and it reduces the size of my u-boot with 6-8 KB. While at it, add -fno-jump-tables too to save a few more bytes. -msingle-pic-base will be in gcc 4.6, however backported patches are available at http://bugs.gentoo.org/show_bug.cgi?id=347281 Signed-off-by: Joakim Tjernlund

PowerPC: Move -fPIC flag to common place

2011-04-11T19:36:41Z

The -fPIC flag belongs with -mrelocatable, move it there. Also change -fPIC to -fpic as this produces smaller binaries. However, currently -mrelocatable promotes -fpic to -fPIC, a fix for this is in upcoming gcc 4.6 or you can apply this small patch to gcc: diff --git a/gcc/config/rs6000/sysv4.h b/gcc/config/rs6000/sysv4.h index 8da8410..e4b8280 100644 --- a/gcc/config/rs6000/sysv4.h +++ b/gcc/config/rs6000/sysv4.h @@ -227,7 +227,8 @@ do { \ } \ \ else if (TARGET_RELOCATABLE) \ - flag_pic = 2; \ + if (!flag_pic) \ + flag_pic = 2; \ } while (0) #ifndef RS6000_BI_ARCH -- Signed-off-by: Joakim Tjernlund

mpc83xx: restrict UTMI PHY configuration to 831x parts

2011-04-05T01:23:20Z

i.e, to those parts that have PHY_CLK_VALID bits in their USB CONTROL registers: mpc8308 WU_INT, PHY_CLK_SEL, USB_EN, WU_INT_EN, ULPI_INT_EN mpc831x PHY_CLK_VALID, WU_INT, CLKIN_SEL, PHY_CLK_SEL, UTMI_PHY_EN, PLL_RESET, REFSEL, OTG_PORT, KEEP_OTG_ON, LSF_EN, USB_EN, ULPI_INT_EN mpc834x USB_EN, ULPI_INT1_EN (MPH only), ULPI_INT0_EN mpc837x USB_EN, ULPI_INT_EN (mpc832x, mpc8360 don't have a USB_EHCI_FSL compatible controller) this prevents non-831x parts from never completing cpu_init_f(), because the (non-existent) PHY_CLK_VALID bit never gets set.

rename _end to __bss_end__

2011-03-27T17:18:37Z

Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang

mpc83xx: Use correct register to calculate clocks.

2011-02-05T23:06:57Z

Use SPMR instead of HRCWL when calculating clocks as HCRWL may be changed and the CPU will not pick up all changes until there is a POR. u-boot will think SPMF has changed and get the clocks wrong. Signed-off-by: Joakim Tjernlund Signed-off-by: Kim Phillips

PowerPC: Add relocation support for -fpic
