Subject: fsl-lsch2: csu: correct the workaround A-010315
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=acb90e8338734004aed6e0cb47585c96611ce9c9;p=u-boot.git

fsl-lsch2: csu: correct the workaround A-010315

The implementation of function set_pcie_ns_access() uses a wrong
argument. The structure array ns_dev has a member 'ind' which is
initialized by CSU_CSLX_*. It should use the 'ind' directly to
address the PCIe's CSL register (CSL_base + CSU_CSLX_PCIE*).
