From mboxrd@z Thu Jan 1 00:00:00 1970 From: Masahiro Yamada Date: Tue, 30 Aug 2016 16:22:23 +0900 Subject: [U-Boot] [PATCH v2 4/4] ARM: armv7: move ARMV7_PSCI_NR_CPUS to Kconfig In-Reply-To: <1472541743-18717-1-git-send-email-yamada.masahiro@socionext.com> References: <1472541743-18717-1-git-send-email-yamada.masahiro@socionext.com> Message-ID: <1472541743-18717-5-git-send-email-yamada.masahiro@socionext.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Move this option to Kconfig and set its default value to 4; this increases the number of supported CPUs for some boards. It consumes 1KB memory per CPU for PSCI stack, but it should not be a big deal, given the amount of memory used for the modern OSes.
