From f98eeb4eb1c52de89dcefeb538029bcecc6dd42d Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 9 Jan 2008 11:27:23 -0600 Subject: [PATCH 01/45] [POWERPC] Fix handling of memreserve if the range lands in highmem There were several issues if a memreserve range existed and happened to be in highmem: * The bootmem allocator is only aware of lowmem so calling reserve_bootmem with a highmem address would cause a BUG_ON * All highmem pages were provided to the buddy allocator Added a lmb_is_reserved() api that we now use to determine if a highem page should continue to be PageReserved or provided to the buddy allocator. Also, we incorrectly reported the amount of pages reserved since all highmem pages are initally marked reserved and we clear the PageReserved flag as we "free" up the highmem pages.

That, in turn, drastically simplifies the code, and drops down line count. As an additional bonus, now there is no need to register MDIO bus for each PHY, all emulated PHYs placed on the platform fixed MDIO bus. There is also no more need to pre-allocate PHYs via .config option, this is all now handled dynamically.

This +header file contains macros that define the microcode binary itself as well as +some other data used in uploading that microcode. The format of these files +do not lend themselves to simple inclusion into other code. Hence, +the need for a more portable format. This section defines that format. + +Instead of distributing a header file, the microcode and related data are +embedded into a binary blob. This blob is passed to the qe_upload_firmware() +function, which parses the blob and performs everything necessary to upload +the microcode. + +All integers are big-endian. See the comments for function +qe_upload_firmware() for up-to-date implementation information. + +This structure supports versioning, where the version of the structure is +embedded into the structure itself. To ensure forward and backwards +compatibility, all versions of the structure must use the same 'qe_header' +structure at the beginning. + +'header' (type: struct qe_header): + The 'length' field is the size, in bytes, of the entire structure, + including all the microcode embedded in it, as well as the CRC (if + present). + + The 'magic' field is an array of three bytes that contains the letters + 'Q', 'E', and 'F'. This is an identifier that indicates that this + structure is a QE Firmware structure. + + The 'version' field is a single byte that indicates the version of this + structure. If the layout of the structure should ever need to be + changed to add support for additional types of microcode, then the + version number should also be changed. + +The 'id' field is a null-terminated string(suitable for printing) that +identifies the firmware. + +The 'count' field indicates the number of 'microcode' structures. There +must be one and only one 'microcode' structure for each RISC processor. +Therefore, this field also represents the number of RISC processors for this +SOC. + +The 'soc' structure contains the SOC numbers and revisions used to match +the microcode to the SOC itself. Normally, the microcode loader should +check the data in this structure with the SOC number and revisions, and +only upload the microcode if there's a match. However, this check is not +made on all platforms. + +Although it is not recommended, you can specify '0' in the soc.model +field to skip matching SOCs altogether. + +The 'model' field is a 16-bit number that matches the actual SOC. The +'major' and 'minor' fields are the major and minor revision numbrs, +respectively, of the SOC. + +For example, to match the 8323, revision 1.0: + soc.model = 8323 + soc.major = 1 + soc.minor = 0 + +'padding' is neccessary for structure alignment. This field ensures that the +'extended_modes' field is aligned on a 64-bit boundary. + +'extended_modes' is a bitfield that defines special functionality which has an +impact on the device drivers. Each bit has its own impact and has special +instructions for the driver associated with it. This field is stored in +the QE library and available to any driver that calles qe_get_firmware_info(). + +'vtraps' is an array of 8 words that contain virtual trap values for each +virtual traps. As with 'extended_modes', this field is stored in the QE +library and available to any driver that calles qe_get_firmware_info(). + +'microcode' (type: struct qe_microcode): + For each RISC processor there is one 'microcode' structure. The first + 'microcode' structure is for the first RISC, and so on. + + The 'id' field is a null-terminated string suitable for printing that + identifies this particular microcode. + + 'traps' is an array of 16 words that contain hardware trap values + for each of the 16 traps. If trap[i] is 0, then this particular + trap is to be ignored (i.e. not written to TIBCR[i]). The entire value + is written as-is to the TIBCR[i] register, so be sure to set the EN + and T_IBP bits if necessary. + + 'eccr' is the value to program into the ECCR register. + + 'iram_offset' is the offset into IRAM to start writing the + microcode. + + 'count' is the number of 32-bit words in the microcode. + + 'code_offset' is the offset, in bytes, from the beginning of this + structure where the microcode itself can be found. The first + microcode binary should be located immediately after the 'microcode' + array. + + 'major', 'minor', and 'revision' are the major, minor, and revision + version numbers, respectively, of the microcode. If all values are 0, + then these fields are ignored. + + 'reserved' is necessary for structure alignment. Since 'microcode' + is an array, the 64-bit 'extended_modes' field needs to be aligned + on a 64-bit boundary, and this can only happen if the size of + 'microcode' is a multiple of 8 bytes. To ensure that, we add + 'reserved'. + +After the last microcode is a 32-bit CRC. It can be calculated using +this algorithm: + +u32 crc32(const u8 *p, unsigned int len) +{ + unsigned int i; + u32 crc = 0; + + while (len--) { + crc ^= *p++; + for (i = 0; i < 8; i++) + crc = (crc >> 1) ^ ((crc & 1) ? 0xedb88320 : 0); + } + return crc; +} + +VI - Sample Code for Creating Firmware Files +============================================ + +A Python program that creates firmware binaries from the header files normally +distributed by Freescale can be found on http://opensource.freescale.com. diff --git a/arch/powerpc/platforms/Kconfig b/arch/powerpc/platforms/Kconfig index ea22cad2cd0a..18f101bcca94 100644 --- a/arch/powerpc/platforms/Kconfig +++ b/arch/powerpc/platforms/Kconfig @@ -265,6 +265,7 @@ config TAU_AVERAGE config QUICC_ENGINE bool select PPC_LIB_RHEAP + select CRC32 help The QUICC Engine (QE) is a new generation of communications coprocessors on Freescale embedded CPUs (akin to CPM in older chips). diff --git a/arch/powerpc/sysdev/qe_lib/qe.c b/arch/powerpc/sysdev/qe_lib/qe.c index 21e01061aca9..3925eae9b0f5 100644 --- a/arch/powerpc/sysdev/qe_lib/qe.c +++ b/arch/powerpc/sysdev/qe_lib/qe.c @@ -25,6 +25,7 @@ #include #include #include +#include #include #include #include @@ -394,3 +395,249 @@ void *qe_muram_addr(unsigned long offset) return (void *)&qe_immr->muram[offset]; } EXPORT_SYMBOL(qe_muram_addr); + +/* The maximum number of RISCs we support */ +#define MAX_QE_RISC 2 + +/* Firmware information stored here for qe_get_firmware_info() */ +static struct qe_firmware_info qe_firmware_info; + +/* + * Set to 1 if QE firmware has been uploaded, and therefore + * qe_firmware_info contains valid data. + */ +static int qe_firmware_uploaded; + +/* + * Upload a QE microcode + * + * This function is a worker function for qe_upload_firmware().
