Overview
|
|
--------
|
|
The LS2080A Development System (QDS) is a high-performance computing,
|
|
evaluation, and development platform that supports the QorIQ LS2080A
|
|
and LS2088A Layerscape Architecture processor. The LS2080AQDS provides
|
|
validation and SW development platform for the Freescale LS2080A, LS2088A
|
|
processor series, with a complete debugging environment.

Environment Variables
|
|
---------------------
|
|
- mcboottimeout: MC boot timeout in milliseconds. If this variable is not defined
|
|
the value CONFIG_SYS_LS_MC_BOOT_TIMEOUT_MS will be assumed.
|
|
|
|
- mcmemsize: MC DRAM block size. If this variable is not defined
|
|
the value CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed.
|
|
|
|
Booting Linux flavors which do not support 48-bit VA (< Linux 3.18)
|
|
-------------------------------------------------------------------
|
|
One needs to use appropriate bootargs to boot Linux flavors which do
|
|
not support 48-bit VA (for e.g. < Linux 3.18) by appending mem=2048M, as shown
|
|
below:
|
|
|
|
=> setenv bootargs 'console=ttyS1,115200 root=/dev/ram
|
|
earlycon=uart8250,mmio,0x21c0600,115200 default_hugepagesz=2m hugepagesz=2m
|
|
hugepages=16 mem=2048M'
|

X-QSGMII-16PORT riser card
|
|
----------------------------
|
|
The X-QSGMII-16PORT is a 4xQSGMII/8xSGMII riser card with eighth SerDes
|
|
interfaces implemented in PCIe form factor board.
|
|
It supports following:
|
|
- Card can operate with up to 4 QSGMII lane simultaneously
|
|
- Card can operate with up to 8 SGMII lane simultaneously
|
|
|
|
Supported card configuration
|
|
- CSEL : ON ON ON ON
|
|
- MSEL1 : ON ON ON ON OFF OFF OFF OFF
|
|
- MSEL2 : OFF OFF OFF OFF ON ON ON ON
|
|
|
|
To enable this card: modify hwconfig to add "xqsgmii" variable.
