* km/common: implement boardId HWkey checks as u-boot cmdThomas Herzmann2011-05-18-0/+156
| | | | | | | | | | | | | | | | | | | | | | | | BoardId and HWKey are used to identify the HW class of a given board. The correct values are stored in the inventory eeprom. During creation time of a boot package the boardId and HWkey for the SW is stored in the default environment and burned into the flash. During boottime the values in the inventory and in the environment are compared to avoid starting of a SW which is not authorized for this board. Some bootpackages are allowed to run on a set of different boardId hwKey. In this case the environment variable boardIdListHex was added to the default environment. In this case the command iterates over the pair values and compares them with the values read from the inventory eeprom. The syntax of such a boardIdListHex value is e.g.: 158_1 159_1 159_2 Signed-off-by: Thomas Herzmann <thomas.herzmann@keymile.com> Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com> Acked-by: Heiko Schocher <hs@denx.de> cc: Wolfgang Denk <wd@denx.de> cc: Detlev Zundel <dzu@denx.de>

| | | | | | | | | | | | | | | | | This patch adds support for the MPC8247 based board mgcoge3ne. Additionaly mgcoge2ne board supprot was removed, because due to the mgcoge3ne, this board is obsolete and not longer maintained. The board is similar to mgcoge.

| | | | | | | | | | | | | | | | | | | | | For the kmsupx5 a new header file was introduced km8321-common.h. Now the common stuff from tuxa1, tuda1 and suvd3 was removed and the new header file included. The defines CONFIG_SYS_PIGGY_BASE and CONFIG_SYS_PIGGY_SIZE are confusing. Because they actually describe the KMBEC FPGA values. The KMBEC FPGA can be PRIO on kmeter1 or upio on mgcoge.

* ppc: add support for ppc based board mgcoge2neHeiko Schocher2011-04-30-2/+2
| | | | | | | | | | | | | | | | | The mgcoge2 board from keymile deploys two different processors. An ARM based Kirkwood for the "unit" part of the SW and a PPC for the "ne" part of the SW. Therefore in Linux and U-Boot the names for the board are mgcoge2un and mgcoge2ne. This patch adds the mgcoge2ne part of the board. The ppc part of mgboge2 is quite similar to mgcoge, therefore a generic header km82xx-common.h was introduced to collect all similiarities. Currently the only difference is that mgcoge2ne has a 64 MB numonyx NOR flash with a single die. The mgcoge has a dual die flash 2*32MB from spansion.

* mgcoge, mgsuvd: add board specific I2C deblocking mechanism.Heiko Schocher2008-10-18-0/+209
As documented in doc/I2C_Edge_Conditions, adding a board specific deblocking mechanism via CFG_I2C_INIT_BOARD for the mgcoge and mgsuvd board. This code was originally written by Keymile in association with Anatech and Atmel in 1998. The Code toggels the SCL until the SCA line goes to HIGH (max. 16 times). And after this, a start condition is sent. This is another approach to deblock the I2C Bus. The soft I2C driver actually sends 9 clocks with SDA High, and then a stop at the end, to deblock the I2C Bus. Maybe we should use the approach from Keymile as the new standard?
