When software sets CPT_AF_CTL[RNM_REQ_EN]=1 and RNM in not producing entropy(i.e., RNM_ENTROPY_STATUS[NORMAL_CNT] < 0x40), the first cycle of the response may be lost due to a conditional clocking issue. Due to this, the subsequent random number stream will be corrupted. So, this patch adds support to ensure RNM_ENTROPY_STATUS[NORMAL_CNT] = 0x40 before writing CPT_AF_CTL[RNM_REQ_EN] = 1, as a workaround.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
