[U-Boot] [PATCH 1/2] powerpc/85xx: Remove DATARATE_*_MHZ defines in static ddr init
by Kumar Gala 01 Feb '11

01 Feb '11

Rather than having #defines DATARATE_*_MHZ, lets just match what we do on the SPD code and convert the DDR frequency into MHZ and just compare with a constant. Based on patch from Poonam Aggrwal.

[U-Boot] [PATCH 1/1] fix min/max macros in common.h
by Aaron Williams 01 Feb '11

01 Feb '11

In some of my work with the Cavium Octeon 64-bit processor I ran into a problem with the min and max macros provided in common.h. The problem occurs if x is 32-bit and y is 64-bit. In this case, y will always be truncated to 32-bits. This patch fixes this problem. -Aaron diff --git a/include/common.h b/include/common.h index d8c912d..cf5c076 100644 --- a/include/common.h +++ b/include/common.h @@ -180,11 +180,13 @@ typedef void (interrupt_handler_t)(void *); * General Purpose Utilities */ #define min(X, Y) \ - ({ typeof (X) __x = (X), __y = (Y); \ + ({ typeof (X) __x = (X); \ + typeof (Y) __y = (Y); \ (__x < __y) ? __x : __y; }) #define max(X, Y) \ - ({ typeof (X) __x = (X), __y = (Y); \ + ({ typeof (X) __x = (X); \ + typeof (Y) __y = (Y); \ (__x > __y) ? __x : __y; }) #define MIN(x, y) min(x, y)

Hello all, My name is Erwan Grâce, I'm French. Here's my issue : I had loaded the Flash memory of an electronic card with 2 RAMdisk which are supposed to be the same. However, when I checked the messages displayed on a screen at boot time, I observed that there were some differences between the 2 RAMdisk : Messages displayed for the 1st RAMdisk : ## Booting image at ffb00000 ... Image Name: Linux-2.6.10_mvlcge401-8560ads Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1662041 Bytes = 1.6 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Uncompressing Kernel Image ... OK ## Loading RAMDisk Image at fc100000 ... Image Name: tcifl.ramdisk Image Type: PowerPC Linux RAMDisk Image (gzip compressed) Data Size: 42466734 Bytes = 40.5 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Loading Ramdisk to 15780000, end 17fffdae ... OK Messages displayed for the 2nd RAMdisk : ## Booting image at ffb00000 ... Image Name: Linux-2.6.10_mvlcge401-8560ads Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1662041 Bytes = 1.6 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Uncompressing Kernel Image ... OK ## Loading RAMDisk Image at fc100000 ... Image Name: tcifl.ramdisk Image Type: PowerPC Linux RAMDisk Image (gzip compressed) Data Size: 42451540 Bytes = 40.5 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Loading Ramdisk to 15783000, end 17fff254 ... OK As you can notice, the 2 RAMdisk seem to be different but I don't know why. I just observe that they have different size and they are not loaded at the same address in RAM memory. I precise that I didn't build this RAMdisk. Can someone help me to understand what is the root cause of these differences, please ? Thank you very much for your help. Best regards, Erwan Grâce
